Method Details

configure

public void configure()
               throws ConfigurationException

Description copied from class: FixedForwardPipe

Checks for correct configuration of forward.

Specified by:

configure in interface IConfigurable

Overrides:

configure in class FixedForwardPipe

Throws:

ConfigurationException - in case it was not able to configure the component.

doPipe

public PipeRunResult doPipe(Message input,
 PipeLineSession session)
                     throws PipeRunException

Description copied from interface: IPipe

This is where the action takes place. Pipes may only throw a PipeRunException, to be handled by the caller of this object. Implementations must either consume the message, or pass it on to the next Pipe in the PipeRunResult. If the result of the Pipe does not depend on the input, like for the FixedResultPipe, the Pipe can schedule the input to be closed at session exit, by calling Message.closeOnCloseOf(PipeLineSession) This allows the previous Pipe to release any resources (e.g. connections) that it might have kept open until the message was consumed. Doing so avoids connections leaking from pools, while it enables efficient streaming processing of data while it is being read from a stream.

Throws:

PipeRunException

getCollection

@Nullable
protected Collection<C,P> getCollection(PipeLineSession session)
                                 throws CollectionException

                                            throws CollectionException

Throws:

addPartToCollection
