Method Detail

pipe

public Instance pipe(Instance carrier)

Description copied from class: Pipe

Process an Instance. This method takes an input Instance, destructively modifies it in some way, and returns it. This is the method by which all pipes are eventually run.

One can create a new concrete subclass of Pipe simply by implementing this method.

Specified by:

pipe in class Pipe

Parameters:

carrier - Instance to be processed.

setGrowAlphabet

public void setGrowAlphabet(boolean growAlphabet)
