Interface AsynchronousChannelStep.ChannelOperation<C extends java.nio.channels.AsynchronousChannel>

Enclosing class:

AsynchronousChannelStep<I,O>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
protected static interface AsynchronousChannelStep.ChannelOperation<C extends java.nio.channels.AsynchronousChannel>

A functional interface used as argument to AsynchronousChannelStep.ChannelCallback.

Method Summary

Modifier and Type	Method and Description
boolean	execute(int nBytesProcessed, C rChannel, java.nio.ByteBuffer rData, AsynchronousChannelStep.ChannelCallback<java.lang.Integer,C> rCallback) Performs an asnychronous channel operation if necessary or returns FALSE.

Method Detail

execute

boolean execute(int nBytesProcessed,
                C rChannel,
                java.nio.ByteBuffer rData,
                AsynchronousChannelStep.ChannelCallback<java.lang.Integer,C> rCallback)
         throws java.lang.Exception

Performs an asnychronous channel operation if necessary or returns FALSE.

Parameters:

nBytesProcessed - The number of bytes that have been processed by a previous invocation

rChannel - The channel to perform the operation on

rData - The byte buffer for the operation data

rCallback - The callback to be invoked (recursively) upon completion of the operation

Returns:

FALSE if a recursive asynchronous execution has been started, TRUE if the operation is complete

Throws:

java.lang.Exception - Any kind of exception may be thrown
