org.infohazard.maverick.transform
Class AbstractTransformStep  

java.lang.Object
  org.infohazard.maverick.transform.AbstractTransformStep

All Implemented Interfaces:

org.infohazard.maverick.flow.TransformStep

Direct Known Subclasses:

StringTransformStep, XMLTransformStep

---

public abstract class AbstractTransformStep

extends java.lang.Object

implements org.infohazard.maverick.flow.TransformStep

Helper class for all transform steps. When extending this class, remember that you are providing the TransformStep interface, so the getResponse(), etc methods are for a *client* to call. You should be sending your output to the methods on getNext(), which is safe to call multiple times. Remember, the goal is to take data written to you and send it on to the next step!
