Package org.apache.http.impl.nio.codecs

Class ChunkDecoder

java.lang.Object

org.apache.http.impl.nio.codecs.AbstractContentDecoder

org.apache.http.impl.nio.codecs.ChunkDecoder

All Implemented Interfaces:

ContentDecoder

public class ChunkDecoder
extends AbstractContentDecoder

Implements chunked transfer coding. The content is received in small chunks. Entities transferred using this encoder can be of unlimited length.

Since:

4.0
