Interface Processor

All Known Subinterfaces:

InputProcessor<J>

All Known Implementing Classes:

DelegatingInputProcessor

public interface Processor

An abstract interface for concurrent processing. Processing is performed by calling the method process(). It is assumed that each Processor can be used only within one thread, but several different Processors can work concurrently. In this case, processing is finished when all of the concurrent Processors are finished.

Method Summary

Modifier and Type	Method and Description
void	finish() Indicate that processing is finished.
void	process() Performs processing using this Processor.

Method Detail

process

void process()
      throws InterruptedException

Performs processing using this Processor. For each Processor object the method should be called only from one thread, but several Processor objects can call this method concurrently. In this case, processing performs concurrently and is finished when all concurrent calls of process() are finished.

Throws:

InterruptedException - if interrupted during processing

finish

void finish()

Indicate that processing is finished. This method should be eventually called after every call of process(). But it is not necessary that every call of process() should be followed by finish(). E.g., it can be followed by process() when it is determined that processing is not yet finished (e.g., due to concurrent computation).
