Class DatatypeFactory

java.lang.Object
  javax.xml.datatype.DatatypeFactory

public abstract class DatatypeFactory
extends Object
extends Object

Factory that creates new javax.xml.datatype Objects that map XML to/from Java Objects.

newInstance() is used to create a new DatatypeFactory. The following implementation resolution mechanisms are used in the following order:

If the system property specified by DATATYPEFACTORY_PROPERTY, "javax.xml.datatype.DatatypeFactory", exists, a class with the name of the property's value is instantiated. Any Exception thrown during the instantiation process is wrapped as a DatatypeConfigurationException.
If the file ${JAVA_HOME}/lib/jaxp.properties exists, it is loaded in a Properties Object. The Properties Object is then queried for the property as documented in the prior step and processed as documented in the prior step.
The services resolution mechanism is used, e.g. META-INF/services/java.xml.datatype.DatatypeFactory. Any Exception thrown during the instantiation process is wrapped as a DatatypeConfigurationException.
The final mechanism is to attempt to instantiate the Class specified by DATATYPEFACTORY_IMPLEMENTATION_CLASS, "javax.xml.datatype.DatatypeFactoryImpl". Any Exception thrown during the instantiation process is wrapped as a DatatypeConfigurationException.

Since:: 1.5

Constructor Detail

DatatypeFactory

protected DatatypeFactory()

Protected constructor to prevent instaniation outside of package.

Use newInstance() to create a DatatypeFactory.

Method Detail

newInstance

public static DatatypeFactory newInstance()
                                   throws DatatypeConfigurationException

Obtain a new instance of a DatatypeFactory.

The implementation resolution mechanisms are defined in this Class's documentation.

Returns:: New instance of a DocumentBuilderFactory
Throws:: DatatypeConfigurationException - If the implementation is not available or cannot be instantiated.

newDuration

public abstract Duration newDuration(String lexicalRepresentation)

Obtain a new instance of a Duration specifying the Duration as its string representation, "PnYnMnDTnHnMnS", as defined in XML Schema 1.0 section 3.2.6.1.

XML Schema Part 2: Datatypes, 3.2.6 duration, defines duration as:

duration represents a duration of time. The value space of duration is a six-dimensional space where the coordinates designate the Gregorian year, month, day, hour, minute, and second components defined in Section 5.5.3.2 of [ISO 8601], respectively. These components are ordered in their significance by their order of appearance i.e. as year, month, day, hour, minute, and second.

All six values are set and availabe from the created Duration

The XML Schema specification states that values can be of an arbitrary size. Implementations may chose not to or be incapable of supporting arbitrarily large and/or small values. An UnsupportedOperationException will be thrown with a message indicating implementation limits if implementation capacities are exceeded.

Parameters:: lexicalRepresentation - String representation of a Duration.
Returns:: New Duration created from parsing the lexicalRepresentation.
Throws:: IllegalArgumentException - If lexicalRepresentation is not a valid representation of a Duration.; UnsupportedOperationException - If implementation cannot support requested values.; NullPointerException - if lexicalRepresentation is null.

newDuration

public abstract Duration newDuration(long durationInMilliSeconds)

Obtain a new instance of a Duration specifying the Duration as milliseconds.

XML Schema Part 2: Datatypes, 3.2.6 duration, defines duration as:

duration represents a duration of time. The value space of duration is a six-dimensional space where the coordinates designate the Gregorian year, month, day, hour, minute, and second components defined in Section 5.5.3.2 of [ISO 8601], respectively. These components are ordered in their significance by their order of appearance i.e. as year, month, day, hour, minute, and second.

All six values are set by computing their values from the specified milliseconds and are availabe using the get methods of the created Duration. The values conform to and are defined by:

ISO 8601:2000(E) Section 5.5.3.2 Alternative format
W3C XML Schema 1.0 Part 2, Appendix D, ISO 8601 Date and Time Formats
XMLGregorianCalendar Date/Time Datatype Field Mapping Between XML Schema 1.0 and Java Representation

The default start instance is defined by GregorianCalendar's use of the start of the epoch: i.e., Calendar.YEAR = 1970, Calendar.MONTH = Calendar.JANUARY, Calendar.DATE = 1, etc. This is important as there are variations in the Gregorian Calendar, e.g. leap years have different days in the month = Calendar.FEBRUARY so the result of Duration.getMonths() and Duration.getDays() can be influenced.

Parameters:: durationInMilliSeconds - Duration in milliseconds to create.
Returns:: New Duration representing durationInMilliSeconds.

`(ZONE_OFFSET + DST_OFFSET) / (601000)` (in minutes)*	`XMLGregorianCalendar.setTimezone(int offset)`^*

*conversion loss of information. It is not possible to represent a java.util.GregorianCalendar daylight savings timezone id in the XML Schema 1.0 date/time datatype representation.

To compute the return value's TimeZone field,

when this.getTimezone() != FIELD_UNDEFINED, create a java.util.TimeZone with a custom timezone id using the this.getTimezone().
else use the GregorianCalendar default timezone value for the host is defined as specified by java.util.TimeZone.getDefault().

Parameters:: cal - java.util.GregorianCalendar used to create XMLGregorianCalendar
Returns:: XMLGregorianCalendar created from java.util.GregorianCalendar
Throws:: NullPointerException - If cal is null.

Constructor allowing for complete value spaces allowed by W3C XML Schema 1.0 recommendation for xsd:dateTime and related builtin datatypes. Note that year parameter supports arbitrarily large numbers and fractionalSecond has infinite precision.

A null value indicates that field isnot set.

Parameters:: year - of XMLGregorianCalendar to be created.; month - of XMLGregorianCalendar to be created.; day - of XMLGregorianCalendar to be created.; hour - of XMLGregorianCalendar to be created.; minute - of XMLGregorianCalendar to be created.; second - of XMLGregorianCalendar to be created.; fractionalSecond - of XMLGregorianCalendar to be created.; timezone - of XMLGregorianCalendar to be created.
Returns:: XMLGregorianCalendar created from specified values.
Throws:: IllegalArgumentException - If any individual parameter's value is outside the maximum value constraint for the field as determined by the Date/Time Data Mapping table in XMLGregorianCalendar or if the composite values constitute an invalid XMLGregorianCalendar instance as determined by XMLGregorianCalendar.isValid().

For example, an instance of gYear can be created invoking this factory with month and day parameters set to DatatypeConstants.FIELD_UNDEFINED.

A DatatypeConstants.FIELD_UNDEFINED value indicates that field isnot set.

Parameters:: year - of XMLGregorianCalendar to be created.; month - of XMLGregorianCalendar to be created.; day - of XMLGregorianCalendar to be created.; timezone - offset in minutes. DatatypeConstants.FIELD_UNDEFINED indicates optional field is not set.
Returns:: XMLGregorianCalendar created from parameter values.
Throws:: IllegalArgumentException - If any individual parameter's value is outside the maximum value constraint for the field as determined by the Date/Time Data Mapping table in XMLGregorianCalendar or if the composite values constitute an invalid XMLGregorianCalendar instance as determined by XMLGregorianCalendar.isValid().
