Description
Interface Summary | |
DataInput | The DataInput interface provides
for reading bytes from a binary stream and
reconstructing from them data in any of
the Java primitive types. |
DataOutput | The DataOutput interface provides
for converting data from any of the Java
primitive types to a series of bytes and
writing these bytes to a binary stream. |
Externalizable | Only the identity of the class of an Externalizable instance is written in the serialization stream and it is the responsibility of the class to save and restore the contents of its instances. |
FileFilter | A filter for abstract pathnames. |
FilenameFilter | Instances of classes that implement this interface are used to filter filenames. |
ObjectInput | ObjectInput extends the DataInput interface to include the reading of objects. |
ObjectInputValidation | Callback interface to allow validation of objects within a graph. |
ObjectOutput | ObjectOutput extends the DataOutput interface to include writing of objects. |
ObjectStreamConstants | Constants written into the Object Serialization Stream. |
Serializable | Serializability of a class is enabled by the class implementing the java.io.Serializable interface. |
Class Summary | |
BufferedInputStream | A BufferedInputStream adds
functionality to another input stream-namely,
the ability to buffer the input and to
support the mark and reset
methods. |
BufferedOutputStream | The class implements a buffered output stream. |
BufferedReader | Read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. |
BufferedWriter | Write text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings. |
ByteArrayInputStream | A ByteArrayInputStream contains
an internal buffer that contains bytes that
may be read from the stream. |
ByteArrayOutputStream | This class implements an output stream in which the data is written into a byte array. |
CharArrayReader | This class implements a character buffer that can be used as a character-input stream. |
CharArrayWriter | This class implements a character buffer that can be used as an Writer. |
DataInputStream | A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way. |
DataOutputStream | A data input stream lets an application write primitive Java data types to an output stream in a portable way. |
File | An abstract representation of file and directory pathnames. |
FileDescriptor | Instances of the file descriptor class serve as an opaque handle to the underlying machine-specific structure representing an open file, an open socket, or another source or sink of bytes. |
FileInputStream | A FileInputStream obtains input bytes
from a file in a file system. |
FileOutputStream | A file output stream is an output stream for writing data to a
File or to a FileDescriptor . |
FilePermission | This class represents access to a file or directory. |
FileReader | Convenience class for reading character files. |
FileWriter | Convenience class for writing character files. |
FilterInputStream | A FilterInputStream contains
some other input stream, which it uses as
its basic source of data, possibly transforming
the data along the way or providing additional
functionality. |
FilterOutputStream | This class is the superclass of all classes that filter output streams. |
FilterReader | Abstract class for reading filtered character streams. |
FilterWriter | Abstract class for writing filtered character streams. |
InputStream | This abstract class is the superclass of all classes representing an input stream of bytes. |
InputStreamReader | An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and translates them into characters according to a specified character encoding. |
LineNumberInputStream | Deprecated. This class incorrectly assumes that bytes adequately represent characters. |
LineNumberReader | A buffered character-input stream that keeps track of line numbers. |
ObjectInputStream | An ObjectInputStream deserializes primitive data and objects previously written using an ObjectOutputStream. |
ObjectInputStream.GetField | Provide access to the persistent fields read from the input stream. |
ObjectOutputStream | An ObjectOutputStream writes primitive data types and graphs of Java objects to an OutputStream. |
ObjectOutputStream.PutField | Provide programatic access to the persistent fields to be written to ObjectOutput. |
ObjectStreamClass | Serialization's descriptor for classes. |
ObjectStreamField | A description of a Serializable field from a Serializable class. |
OutputStream | This abstract class is the superclass of all classes representing an output stream of bytes. |
OutputStreamWriter | Write characters to an output stream, translating characters into bytes according to a specified character encoding. |
PipedInputStream | A piped input stream should be connected to a piped output stream; the piped input stream then provides whatever data bytes are written to the piped output stream. |
PipedOutputStream | A piped output stream can be connected to a piped input stream to create a communications pipe. |
PipedReader | Piped character-input streams. |
PipedWriter | Piped character-output streams. |
PrintStream | A PrintStream adds functionality to another output stream,
namely the ability to print representations of various data values
conveniently. |
PrintWriter | Print formatted representations of objects to a text-output stream. |
PushbackInputStream | A PushbackInputStream adds
functionality to another input stream, namely
the ability to "push back" or "unread"
one byte. |
PushbackReader | A character-stream reader that allows characters to be pushed back into the stream. |
RandomAccessFile | Instances of this class support both reading and writing to a random access file. |
Reader | Abstract class for reading character streams. |
SequenceInputStream | A SequenceInputStream represents
the logical concatenation of other input
streams. |
SerializablePermission | This class is for Serializable permissions. |
StreamTokenizer | The StreamTokenizer class takes an input stream and
parses it into "tokens", allowing the tokens to be
read one at a time. |
StringBufferInputStream | Deprecated. This class does not properly convert characters into bytes. |
StringReader | A character stream whose source is a string. |
StringWriter | A character stream that collects its output in a string buffer, which can then be used to construct a string. |
Writer | Abstract class for writing to character streams. |
Exception Summary | |
CharConversionException | base class for character conversion exceptions |
EOFException | Signals that an end of file or end of stream has been reached unexpectedly during input. |
FileNotFoundException | Signals that an attempt to open the file denoted by a specified pathname has failed. |
InterruptedIOException | Signals that an I/O operation has been interrupted. |
InvalidClassException | Thrown when the Serialization runtime detects one of the following problems with a Class. |
InvalidObjectException | Indicates that one or more deserialized objects failed validation tests. |
IOException | Signals that an I/O exception of some sort has occurred. |
NotActiveException | Thrown when serialization or deserialization is not active. |
NotSerializableException | Thrown when an instance is required to have a Serializable interface. |
ObjectStreamException | Superclass of all exceptions specific to Object Stream classes. |
OptionalDataException | Unexpected data appeared in an ObjectInputStream trying to read an Object. |
StreamCorruptedException | Thrown when control information that was read from an object stream violates internal consistency checks. |
SyncFailedException | |
UnsupportedEncodingException | The Character Encoding is not supported |
UTFDataFormatException | Signals that a malformed UTF-8 string has been read in a data input stream or by any class that implements the data input interface. |
WriteAbortedException |
Provides for system input and output through data streams, serialization and the file system.
