add

public void add(S s)

reset

public void reset()

Description copied from interface: Pipe

A pipe may maintain state. Reset is used to remove state. The general use case for reset() is to reuse a pipe in another computation without having to create a new Pipe object. An implementation of this method should be recursive whereby the starts (if a Pipe) should have this method called on it.

Specified by:

reset in interface Pipe<S,S>

Overrides:

reset in class AbstractPipe<S,S>
