Class ChunkEncoder

java.lang.Object

org.apache.http.impl.nio.codecs.AbstractContentEncoder

org.apache.http.impl.nio.codecs.ChunkEncoder

All Implemented Interfaces:

ContentEncoder

public class ChunkEncoder
extends AbstractContentEncoder

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

Since:

4.0

Constructor Detail

ChunkEncoder

public ChunkEncoder(java.nio.channels.WritableByteChannel channel,
                    SessionOutputBuffer buffer,
                    HttpTransportMetricsImpl metrics,
                    int fragementSizeHint)

Parameters:

channel - underlying channel.

buffer - session buffer.

metrics - transport metrics.

fragementSizeHint - fragment size hint defining an minimal size of a fragment that should be written out directly to the channel bypassing the session buffer. Value 0 disables fragment buffering.

Since:

4.3
