Constructor Detail

AbstractPipeline

public AbstractPipeline(Acceptor<? super E,? extends R> downstream)

Construct an AbstractPipeline with the given downstream Acceptor.

Parameters:

downstream - the Acceptor

Method Detail

getDownstream

public Acceptor<? super E,? extends R> getDownstream()

Get the downstream Acceptor

Specified by:

getDownstream in interface BasePipeline<R>

Returns:

the Acceptor

close

public void close()
           throws Exception

Close the pipeline.

Specified by:

close in interface AutoCloseable

Overrides:

close in class BaseAbstractAcceptor<R>

Throws:

Exception - if thrown by the downstream or superclass close() functions

emit

public void emit(E value)

Emit a value to the downstream IntAcceptor.

Specified by:

emit in interface Pipeline<A,E,R>

Parameters:

value - the value to be forwarded

flush

public void flush()

Propagate the flush operation to the downstream acceptor.

Specified by:

flush in interface BaseAcceptor<R>
