Interface Summary |
| Closeable |
A Closeable class represents a stream of
data, which can be closed when it is no longer needed. |
| DataInput |
This interface is implemented by classes that can data from streams
into Java primitive types. |
| DataOutput |
This interface is implemented by classes that can wrte data to streams
from Java primitive types. |
| Externalizable |
This interface provides a way that classes can completely control how
the data of their object instances are written and read to and from
streams. |
| FileFilter |
This interface has one method which is used for filtering pathnames
returned in a pathname listing. |
| FilenameFilter |
This interface has one method which is used for filtering filenames
returned in a directory listing. |
| Flushable |
A Flushable class represents a stream of
data, for which internally buffered data can be `flushed'. |
| ObjectInput |
This interface extends the DataInput interface to provide a
facility to read objects as well as primitive types from a stream. |
| ObjectInputValidation |
This class allows an object to validate that it is valid after
deserialization has run completely for it and all dependent objects. |
| ObjectOutput |
This interface extends DataOutput to provide the additional
facility of writing object instances to a stream. |
| ObjectStreamConstants |
This interface contains constants that are used in object
serialization. |
| Serializable |
This interface has no methods. |

This is a convenience class for writing to files. |
| FilterInputStream |
This is the common superclass of all standard classes that filter
input. |

This class is the common superclass of output stream classes that
filter the output they write. |
| FilterReader |
This is the common superclass of all standard classes that filter
input. |

This class is the common superclass of output character stream classes
that filter the output they write. |
| InputStream |

input as a stream of bytes. |
| InputStreamReader |
This class reads characters from a byte input stream. |
| LineNumberInputStream |
Deprecated. This class is deprecated in favor if
LineNumberReader because it operates on ASCII bytes
instead of an encoded character stream. |
| LineNumberReader |
This class functions like a standard Reader except that it
counts line numbers, and canonicalizes newline characters. |
| ObjectInputStream |
|
| ObjectInputStream.GetField |
This class allows a class to specify exactly which fields should
be read, and what values should be read for these fields. |

|
| ObjectOutputStream |
An ObjectOutputStream can be used to write objects
as well as primitive data in a platform-independent manner to an
OutputStream. |
| ObjectOutputStream.PutField |
This class allows a class to specify exactly which fields should
be written, and what values should be written for these fields. |
| ObjectStreamClass |
|
| ObjectStreamClass.InterfaceComparator |
|
| ObjectStreamClass.MemberComparator |
|
| ObjectStreamField |
This class intends to describe the field of a class for the serialization
subsystem. |
| OutputStream |
This abstract class forms the base of the hierarchy of classes that
write output as a stream of bytes. |
| OutputStreamWriter |
This class writes characters to an output stream that is byte oriented
It converts the chars that are written to bytes using an encoding layer,
which is specific to a particular encoding standard. |
