Pipeline
when data is available for processing. The implementation can
modify the stream by discarding bytes from the stream and
inserting new data. If it doesn't wish to modify the stream,
it should skip the relevant parts, so that it will be processed
by the next filter in the pipeline.
An implementation is not required to process (skip or discard)
all the data available on each invocation. If after the invocation
of this method Stream.available()
is non zero, the remaining
(unprocessed) data will be available again during the next invocation
of the filter.
