All Implemented Interfaces:

org.xnio.conduits.Conduit, org.xnio.conduits.SinkConduit, org.xnio.conduits.StreamSinkConduit

public final class HeadStreamSinkConduit
extends org.xnio.conduits.AbstractStreamSinkConduit<org.xnio.conduits.StreamSinkConduit>

A conduit that discards all data written to it. This allows head requests to 'just work', as all data written will be discarded.

Constructor Detail

HeadStreamSinkConduit

public HeadStreamSinkConduit(org.xnio.conduits.StreamSinkConduit next,
                     ConduitListener<? super HeadStreamSinkConduit> finishListener)

Construct a new instance.

Parameters:

next - the next channel

contentLength - the content length

configurable - true if this instance should pass configuration to the next

propagateClose - true if this instance should pass close to the next

finishListener - the listener to call when the channel is closed or the length is reached
