Class StandardStep<T,U>

java.lang.Object
  org.galagosearch.tupleflow.StandardStep<T,U>

All Implemented Interfaces:

Processor<T>, Source<U>, Step

Direct Known Subclasses:

Sorter, XMLMinimum

public abstract class StandardStep<T,U>
extends java.lang.Object
implements Processor<T>, Source<U>

This is the base class for most TupleFlow steps. Most TupleFlow steps convert data from some type T to some type U, then call the process method on some other processor. This class abstracts the details of implementing that kind of class.
