Class BaseDataOutputStream

java.lang.Object

java.io.OutputStream

org.jgroups.util.BaseDataOutputStream

All Implemented Interfaces:

Closeable, DataOutput, Flushable, AutoCloseable

Direct Known Subclasses:

ByteArrayDataOutputStream, ByteBufferOutputStream, PartialOutputStream

public abstract class BaseDataOutputStream
extends OutputStream
implements DataOutput

Implements DataOutput in a generic manner, so that subclasses can implement specific behavior. Some write() methods are abstract and need to be implemennted in subclasses. Filed pos points to the current write-position.

Since:

5.0
