Class ChainProcessorSelector

java.lang.Object
  org.glassfish.grizzly.ChainProcessorSelector

All Implemented Interfaces:

java.lang.Iterable<ProcessorSelector>, java.util.Collection<ProcessorSelector>, java.util.List<ProcessorSelector>, ProcessorSelector

public class ChainProcessorSelector
extends java.lang.Object
implements ProcessorSelector, java.util.List<ProcessorSelector>

ProcessorSelector implementation, which acts like wrapper for chain of ProcessorSelectors. So, when ProcessorSelector.select(IOEvent, Connection) operation is called - it delegates selecting to the first ProcessorSelector from chain. If first ProcessorSelector returns not null Processor - ChainProcessorSelector returns it as result, otherwise next ProcessorSelector will be taken from chain... etc
