Constructor Detail

PipelineImpl

public PipelineImpl()

Superclass constructor.

PipelineImpl

public PipelineImpl(Collection<? extends IPipe> c)

Superclass constructor.

Parameters:

c - A set of pipes.

Method Detail

check

public boolean check(IChannel channel)
              throws AbortException

Description copied from interface: IPipe

Check if a pipe must perform something on channel. If the channel is corrupted the pipe must throw AbortException.

Specified by:

check in interface IPipe

Parameters:

channel - The information channel.

Returns:

true, if pipe must perform something on channel, false, otherwise.

Throws:

AbortException - If the channel is corrupted.

process

public IChannel process(IChannel channel)
                 throws AbortException,
                        PipelineException

Description copied from interface: IPipe

Perform some transformation over the channel.

Specified by:

process in interface IPipe

Parameters:

channel - The channel.

Returns:

The pipe itself.

Throws:

AbortException - On processing errors.

PipelineException - On processing errors.

Description copied from interface: IPipeline

Add a listener.

Specified by:

addPipelineListener in interface IPipeline

Parameters:

listener - A listener.

removePipelineListener

public void removePipelineListener(IPipeListener listener)

Description copied from interface: IPipeline

Remove a listener.

Specified by:

removePipelineListener in interface IPipeline

Parameters:

listener - A listener.
