net.nuke24.tscript34.p0010.ducer.DucerState<I,O>

public class DucerState<I,O>
extends Object

The state of a stream processor, including queued-byt-not-yet-consumed input data, and output data. Input and output may be independently closed. Input may be closed before all data is consumed.

Constructor Details

DucerState

public DucerState(Function<DucerChunk<I>,DucerState<I,O>> processor,
 InputPortState<I> input,
 DucerChunk<O> output)

Method Details

process

public DucerState<I,O> process(DucerChunk<I> input)

isDone

public boolean isDone()

If true, that means that this Danducer has finished doing all the work it will ever do. It will neither consume input nor generate output, so feel free to stop simulating it.

closeInput

public DucerState<I,O> closeInput()

For use by the internal processor. To indicate end of input data, call process() with chunk that isEnd. Return a new state identical to this one but whose input port is closed.

closeOutput

public DucerState<I,O> closeOutput()

For use by internal processor. Return a new state identical to this one but whose input port is closed.

close

public DucerState<I,O> close()

For use by internal processor. Return a new state identical to this one but whose input and output ports are closed, which implies that this Danducer 'isDone'
