Method Detail

isEof

public boolean isEof()

Description copied from interface: Source

Overrides:

isEof in class BasicSource

Returns:

true if the source is at EOF

internalGetNextMessage

protected MessageAndRouting internalGetNextMessage(StreamProcessingContext spc)
                                            throws IOException,
                                                   InterruptedException

Description copied from class: BasicSource

Get the next pending message, if any. This won't be called after a noteEndOfStream() call. The caller handles back-off, so it's not necessary to force a sleep during this call. The object has the instance synchronization lock during this call.

Specified by:

internalGetNextMessage in class BasicSource

Returns:

the next message, or null

Throws:

IOException

InterruptedException
