The event's id.

See Also:: AWTEvent.getID(), AWTEvent.AWTEvent(java.lang.Object, int)

consumed

boolean consumed

Controls whether or not the event is sent back down to the peer once the source has processed it - false means it's sent to the peer; true means it's not. Semantic events always have a 'true' value since they were generated by the peer in response to a low-level event.

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
                        ClassNotFoundException

Reads default serializable fields from the stream. Reads from the stream a string and an array of bytes as additional data.

Serial Data:

The String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. It will usually be null for the predefined profiles.

If the string is recognized as a constant name for predefined color space the object will be resolved into profile obtained with getInstance(int cspace) and the profile data are ignored. Otherwise the object will be resolved into profile obtained with getInstance(byte[] data).

Throws:

IOException - thrown by ObjectInputStream.

ClassNotFoundException - thrown by ObjectInputStream.

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Writes default serializable fields to the stream. Writes a string and an array of bytes to the stream as additional data.

Serial Data:: The String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.
The byte[] array is the profile data for the profile. For predefined color spaces null is written instead of the profile data. If in the future versions of Java API new predefined color spaces will be added, future versions of this class may choose to write for new predefined color spaces not only the color space name, but the profile data as well so that older versions could still deserialize the object.
Throws:: IOException - thrown by ObjectInputStream.

If the resulting FlavorMap is null, this object's FlavorMap is set to the default FlavorMap for this thread's ClassLoader. Next, this object's listeners are deserialized by reading a null-terminated sequence of 0 or more key/value pairs from the stream:

If a key object is a String equal to dragSourceListenerK, a DragSourceListener is deserialized using the corresponding value object and added to this DragSource.
If a key object is a String equal to dragSourceMotionListenerK, a DragSourceMotionListener is deserialized using the corresponding value object and added to this DragSource.

readObject

private void readObject(ObjectInputStream in)
                 throws IOException,
                        ClassNotFoundException

readObject for custom serialization.

This method reads this object's serialized form for this class as follows:

The readObject method is invoked on in to read this object's unique identifier (a UID instance).

Next, the readUTF method is invoked on in to read the external ref type name of the RemoteRef instance for this object's activator. Next, the RemoteRef instance is created of an implementation-specific class corresponding to the external ref type name (returned by readUTF), and the readExternal method is invoked on that RemoteRef instance to read the external form corresponding to the external ref type name.

Note: If the external ref type name is "UnicastRef", "UnicastServerRef", "UnicastRef2", "UnicastServerRef2", "ActivatableRef", or "ActivatableServerRef", a corresponding implementation-specific class must be found, and its readExternal method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a ClassNotFoundException will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case the RemoteRef will be an instance of that implementation-specific class.

writeObject

private void writeObject(ObjectOutputStream out)
                  throws IOException,
                         ClassNotFoundException

writeObject for custom serialization.

This method writes this object's serialized form for this class as follows:

The writeObject method is invoked on out passing this object's unique identifier (a UID instance) as the argument.

Next, the getRefClass method is invoked on the activator's RemoteRef instance to obtain its external ref type name. Next, the writeUTF method is invoked on out with the value returned by getRefClass, and then the writeExternal method is invoked on the RemoteRef instance passing out as the argument.

Serial Data:: The serialized data for this class comprises a java.rmi.server.UID (written with ObjectOutput.writeObject) followed by the external ref type name of the activator's RemoteRef instance (a string written with ObjectOutput.writeUTF), followed by the external form of the RemoteRef instance as written by its writeExternal method.
The external ref type name of the RemoteRef instance is determined using the definitions of external ref type names specified in the RemoteObject writeObject method serialData specification. Similarly, the data written by the writeExternal method and read by the readExternal method of RemoteRef implementation classes corresponding to each of the defined external ref type names is specified in the RemoteObject writeObject method serialData specification.; IOException; ClassNotFoundException

readObject

private void readObject(ObjectInputStream in)
                 throws IOException,
                        ClassNotFoundException

readObject for custom serialization.

This method reads this object's serialized form for this class as follows:

The readUTF method is invoked on in to read the external ref type name for the RemoteRef instance to be filled in to this object's ref field. If the string returned by readUTF has length zero, the readObject method is invoked on in, and than the value returned by readObject is cast to RemoteRef and this object's ref field is set to that value. Otherwise, this object's ref field is set to a RemoteRef instance that is created of an implementation-specific class corresponding to the external ref type name returned by readUTF, and then the readExternal method is invoked on this object's ref field.

If the external ref type name is "UnicastRef", "UnicastServerRef", "UnicastRef2", "UnicastServerRef2", "ActivatableRef", or "ActivatableServerRef", a corresponding implementation-specific class must be found, and its readExternal method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a ClassNotFoundException will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case this object's ref field will be set to an instance of that implementation-specific class.

writeObject

private void writeObject(ObjectOutputStream out)
                  throws IOException,
                         ClassNotFoundException

writeObject for custom serialization.

This method writes this object's serialized form for this class as follows:

The getRefClass method is invoked on this object's ref field to obtain its external ref type name. If the value returned by getRefClass was a non-null string of length greater than zero, the writeUTF method is invoked on out with the value returned by getRefClass, and then the writeExternal method is invoked on this object's ref field passing out as the argument; otherwise, the writeUTF method is invoked on out with a zero-length string (""), and then the writeObject method is invoked on out passing this object's ref field as the argument.

Serial Data:

The serialized data for this class comprises a string (written with ObjectOutput.writeUTF) that is either the external ref type name of the contained RemoteRef instance (the ref field) or a zero-length string, followed by either the external form of the ref field as written by its writeExternal method if the string was of non-zero length, or the serialized form of the ref field as written by passing it to the serialization stream's writeObject if the string was of zero length.

If this object is an instance of java.rmi.server.RemoteStub that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are not used, the external ref type name is "UnicastRef". If this object is an instance of RemoteStub that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are used, the external ref type name is "UnicastRef2". If this object is an instance of RemoteStub that was returned from any of the java.rmi.activation.Activatable.exportObject methods, the external ref type name is "ActivatableRef". If this object is an instance of RemoteStub that was returned from the RemoteObject.toStub method (and the argument passed to toStub was not itself a RemoteStub), the external ref type name is a function of how the remote object passed to toStub was exported, as described above. If this object is an instance of RemoteStub that was originally created via deserialization, the external ref type name is the same as that which was read when this object was deserialized.

If this object is an instance of java.rmi.server.UnicastRemoteObject that does not use custom socket factories, the external ref type name is "UnicastServerRef". If this object is an instance of UnicastRemoteObject that does use custom socket factories, the external ref type name is "UnicastServerRef2".

If this object is an instance of java.rmi.activation.Activatable, the external ref type name is "ActivatableServerRef".

Following is the data that must be written by the writeExternal method and read by the readExternal method of RemoteRef implementation classes that correspond to the each of the defined external ref type names:

For "UnicastRef":

the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
the port of the referenced remote object, written by DataOutput.writeInt(int)
the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a null client socket factory:

the byte value 0x00 (indicating null client socket factory), written by DataOutput.writeByte(int)
the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
the port of the referenced remote object, written by DataOutput.writeInt(int)
the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a non-null client socket factory:

the byte value 0x01 (indicating non-null client socket factory), written by DataOutput.writeByte(int)
the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
the port of the referenced remote object, written by DataOutput.writeInt(int)
a client socket factory (object of type java.rmi.server.RMIClientSocketFactory), written by passing it to an invocation of writeObject on the stream instance
the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
the boolean value false, written by DataOutput.writeBoolean(boolean)

For "ActivatableRef" with a null nested remote reference:

an instance of java.rmi.activation.ActivationID, written by passing it to an invocation of writeObject on the stream instance
a zero-length string (""), written by DataOutput.writeUTF(String)

For "ActivatableRef" with a non-null nested remote reference:

an instance of java.rmi.activation.ActivationID, written by passing it to an invocation of writeObject on the stream instance
the external ref type name of the nested remote reference, which must be "UnicastRef2", written by DataOutput.writeUTF(String)
the external form of the nested remote reference, written by invoking its writeExternal method with the stream instance (see the description of the external form for "UnicastRef2" above)

For "UnicastServerRef", "UnicastServerRef2", and "ActivatableServerRef", no data is written by the writeExternal method or read by the readExternal method.

First, read the default serializable fields from the stream. Then if serialVersionOnStream is less than 1, indicating that the stream was written by JDK 1.1, initialize useExponentialNotation to false, since it was not present in JDK 1.1. Finally, set serialVersionOnStream back to the maximum allowed value so that default serialization will work properly if this object is streamed out again.

If the minimum or maximum integer digit count is larger than DOUBLE_INTEGER_DIGITS or if the minimum or maximum fraction digit count is larger than DOUBLE_FRACTION_DIGITS, then the stream data is invalid and this method throws an InvalidObjectException.

Stream versions older than 2 will not have the affix pattern variables posPrefixPattern etc. As a result, they will be initialized to null, which means the affix strings will be taken as literal values. This is exactly what we want, since that corresponds to the pre-version-2 behavior.

writeObject

private void writeObject(ObjectOutputStream stream)
                  throws IOException

Save the state of this object to a stream (i.e., serialize it). Ideally, Calendar would only write out its state data and the current time, and not write any field data out, such as fields[], isTimeSet, areFieldsSet, and isSet[]. nextStamp also should not be part of the persistent state. Unfortunately, this didn't happen before JDK 1.1 shipped. To be compatible with JDK 1.1, we will always have to write out the field values and state flags. However, nextStamp can be removed from the serialization stream; this will probably happen in the near future.

Serialized Fields

fields

int[] fields

The field values for the currently set time for this calendar. This is an array of FIELD_COUNT integers, with index values ERA through DST_OFFSET.

isSet

areFieldsSet

boolean areFieldsSet

True if fields[] are in sync with the currently set time. If false, then the next attempt to get the value of a field will force a recomputation of all fields from the current value of time.

lenient

boolean lenient

True if this calendar allows out-of-range field values during computation of time from fields[].

See Also:: Calendar.setLenient(boolean)

zone

TimeZone zone

The TimeZone used by this calendar. Calendar uses the time zone data to translate between locale and GMT time.

The number of days required for the first week in a month or year, with possible values from 1 to 7. This is a locale-dependent value.

nextStamp

int nextStamp

The next available value for stamp[], an internal array. This actually should not be written out to the stream, and will probably be removed from the stream in the near future. In the meantime, a value of MINIMUM_USER_STAMP should be used.

serialVersionOnStream

int serialVersionOnStream

The version of the serialized data on the stream. Possible values:

0 or not present on stream: JDK 1.1.5 or earlier.

readObject

private void readObject(ObjectInputStream stream)
                 throws IOException,
                        ClassNotFoundException

Reconstitute this object from a stream (i.e., deserialize it). We handle both JDK 1.1 binary formats and full formats with a packed byte array.

writeObject

private void writeObject(ObjectOutputStream stream)
                  throws IOException

Save the state of this object to a stream (i.e., serialize it).

Serial Data:: We write out two formats, a JDK 1.1 compatible format, using DOW_IN_MONTH_MODE rules, in the required section, followed by the full rules, in packed format, in the optional section. The optional section will be ignored by JDK 1.1 code upon stream in.
Contents of the optional section: The length of a byte array is emitted (int); this is 4 as of this release. The byte array of the given length is emitted. The contents of the byte array are the true values of the fields startDay, startDayOfWeek, endDay, and endDayOfWeek. The values of these fields in the required section are approximate values suited to the rule mode DOW_IN_MONTH_MODE, which is the only mode recognized by JDK 1.1.; IOException

Serialized Fields

startMonth

int startMonth

The month in which daylight saving time starts. This value must be between Calendar.JANUARY and Calendar.DECEMBER inclusive. This value must not equal endMonth.

If useDaylight is false, this value is ignored.

startDay

int startDay

This field has two possible interpretations:

startMode == DOW_IN_MONTH

startDay indicates the day of the month of startMonth on which daylight saving time starts, from 1 to 28, 30, or 31, depending on the startMonth.

startMode != DOW_IN_MONTH

startDay indicates which startDayOfWeek in th month startMonth daylight saving time starts on. For example, a value of +1 and a startDayOfWeek of Calendar.SUNDAY indicates the first Sunday of startMonth. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.

If useDaylight is false, this value is ignored.

startDayOfWeek

int startDayOfWeek

The day of the week on which daylight saving time starts. This value must be between Calendar.SUNDAY and Calendar.SATURDAY inclusive.

If useDaylight is false or startMode == DAY_OF_MONTH, this value is ignored.

startTime

int startTime

The time in milliseconds after midnight at which daylight saving time starts. This value is expressed as wall time, standard time, or UTC time, depending on the setting of startTimeMode.

If useDaylight is false, this value is ignored.

startTimeMode

The month in which daylight saving time ends. This value must be between Calendar.JANUARY and Calendar.UNDECIMBER. This value must not equal startMonth.

If useDaylight is false, this value is ignored.

endDay

int endDay

This field has two possible interpretations:

endMode == DOW_IN_MONTH

endDay indicates the day of the month of endMonth on which daylight saving time ends, from 1 to 28, 30, or 31, depending on the endMonth.

endMode != DOW_IN_MONTH

endDay indicates which endDayOfWeek in th month endMonth daylight saving time ends on. For example, a value of +1 and a endDayOfWeek of Calendar.SUNDAY indicates the first Sunday of endMonth. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.

If useDaylight is false, this value is ignored.

endDayOfWeek

int endDayOfWeek

The day of the week on which daylight saving time ends. This value must be between Calendar.SUNDAY and Calendar.SATURDAY inclusive.

If useDaylight is false or endMode == DAY_OF_MONTH, this value is ignored.

The format of endTime, either WALL_TIME, STANDARD_TIME, or UTC_TIME.

Since:: 1.3

startYear

int startYear

The year in which daylight saving time is first observed. This is an AD value. If this value is less than 1 then daylight saving time is observed for all AD years.

If useDaylight is false, this value is ignored.

rawOffset

int rawOffset

The offset in milliseconds between this zone and GMT. Negative offsets are to the west of Greenwich. To obtain local standard time, add the offset to GMT time. To obtain local wall time it may also be necessary to add dstSavings.

useDaylight

boolean useDaylight

A boolean value which is true if and only if this zone uses daylight saving time. If this value is false, several other fields are ignored.

monthLength

byte[] monthLength

This field was serialized in JDK 1.1, so we have to keep it that way to maintain serialization compatibility. However, there's no need to recreate the array each time we create a new time zone.

An array of bytes containing the values {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}. This is ignored as of the Java 2 platform v1.2, however, it must be streamed out for compatibility with JDK 1.1.

startMode

int startMode

Variables specifying the mode of the start rule. Takes the following values:

DOM_MODE: Exact day of week; e.g., March 1.
DOW_IN_MONTH_MODE: Day of week in month; e.g., last Sunday in March.
DOW_GE_DOM_MODE: Day of week after day of month; e.g., Sunday on or after March 15.
DOW_LE_DOM_MODE: Day of week before day of month; e.g., Sunday on or before March 15.

The setting of this field affects the interpretation of the startDay field.

If useDaylight is false, this value is ignored.

Since:: 1.1.4

endMode

int endMode

Variables specifying the mode of the end rule. Takes the following values:

DOM_MODE: Exact day of week; e.g., March 1.

DOW_GE_DOM_MODE: Day of week after day of month; e.g., Sunday on or after March 15.
DOW_LE_DOM_MODE: Day of week before day of month; e.g., Sunday on or before March 15.

The setting of this field affects the interpretation of the endDay field.

If useDaylight is false, this value is ignored.

Since:: 1.1.4

dstSavings

int dstSavings

A positive value indicating the amount of time saved during DST in milliseconds. Typically one hour (3600000); sometimes 30 minutes (1800000).

If useDaylight is false, this value is ignored.

Since:: 1.1.4

serialVersionOnStream

int serialVersionOnStream

The version of the serialized data on the stream. Possible values:

0 or not present on stream: JDK 1.1.3 or earlier.
1: JDK 1.1.4 or later. Includes three new fields: startMode, endMode, and dstSavings.
2: JDK 1.3 or later. Includes two new fields: startTimeMode and endTimeMode.

When streaming out this class, the most recent format and the highest allowable serialVersionOnStream is written.
