setTargetProcessing

public void setTargetProcessing(boolean lookForAndProcessTarget)

Description copied from class: Pipe

Set whether input is taken from target field of instance during processing. If argument is false, don't expect to find input material for the target. By default, this is true.

Overrides:

setTargetProcessing in class Pipe

newIteratorFrom

public java.util.Iterator<Instance> newIteratorFrom(java.util.Iterator<Instance> source)

Description copied from class: Pipe

Given an InstanceIterator, return a new InstanceIterator whose instances have also been processed by this pipe. If you override this method, be sure to check and obey this pipe's skipIfFalse(Instance) method.

Overrides:

newIteratorFrom in class Pipe

size

public int size()

getPipe

public Pipe getPipe(int index)

pipes

public java.util.ArrayList<Pipe> pipes()

Allows access to the underlying collection of Pipes. Use with caution.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
