Package org.apache.hc.core5.http.impl.nio

Class ChunkDecoder

java.lang.Object

org.apache.hc.core5.http.impl.nio.AbstractContentDecoder

org.apache.hc.core5.http.impl.nio.ChunkDecoder

All Implemented Interfaces:

ContentDecoder

public class ChunkDecoder
extends AbstractContentDecoder

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

Since:

4.0

Overrides:

getTrailers in class AbstractContentDecoder

Returns:

list of trailers

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
