Package org.jgroups.util

Class PartialOutputStream

java.lang.Object

org.jgroups.util.BaseDataOutputStream

org.jgroups.util.PartialOutputStream

All Implemented Interfaces:

java.io.DataOutput

public class PartialOutputStream
extends BaseDataOutputStream

Decorates an output stream (DataOutput) and writes only a subset [start..end] (both indices inclusive) of the original data to the underlying output stream.
Example:

start=5, length=5: range=[5..9], bytes are written for positions 5,6,7,8,9 (5 bytes)

Since:

5.0
