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.
