All Implemented Interfaces:

Callback, Invocable

Enclosing class:

HttpOutput

private class HttpOutput.ReadableByteChannelWritingCB
extends HttpOutput.NestedChannelWriteCB

An iterating callback that will take content from a ReadableByteChannel and write it to the HttpChannel. A ByteBuffer of size HttpOutput.getBufferSize() is used that will be direct if HttpChannel.useDirectBuffers() is true. This callback is passed to the HttpChannel.write(ByteBuffer, boolean, Callback) to be notified as each buffer is written and only once all the input is consumed will the wrapped Callback.succeeded() method be called.

Description copied from class: IteratingCallback

Method called by IteratingCallback.iterate() to process the sub task.

Implementations must start the asynchronous execution of the sub task (if any) and return an appropriate action:

• IteratingCallback.Action.IDLE when no sub tasks are available for execution but the overall job is not completed yet
• IteratingCallback.Action.SCHEDULED when the sub task asynchronous execution has been started
• IteratingCallback.Action.SUCCEEDED when the overall job is completed

Specified by:

process in class IteratingCallback

Returns:

the appropriate Action

Throws:

Exception

onCompleteFailure

public void onCompleteFailure(Throwable x)

Description copied from class: IteratingCallback

Invoked when the overall task has completed with a failure.

Overrides:

onCompleteFailure in class HttpOutput.NestedChannelWriteCB

Parameters:

x - the throwable to indicate cause of failure
