void setNode(Node node)

Associates a graph Node with this transform.

Node getNode()

return a graph Node associated with this transform, or null if no graph node is associated

TransformationGraph getGraph()

Returns a TransformationGraph associated with this transform, or null if no graph is associated.

void preExecute()

Called during each graph run before the transform is executed. May be used to allocate and initialize resources required by the transform. All resources allocated within this method should be released by the postExecute() method.

void postExecute(TransactionMethod transactionMethod)

Called during each graph run after the entire transform was executed. Should be used to free any resources allocated within the preExecute() method.

String getMessage()

Called to report any user-defined error message if an error occurred during the transform and the transform returned value less than or equal to -2. It is called when either append(), count(), generate(), getOutputPort(), transform(), or updateTransform() or any of their OnError() counterparts returns value less than or equal to -2.

void finished() (deprecated)

Called at the end of the transform after all input data records were processed.

void reset() (deprecated)

Resets the transform to the initial state (for another execution). This method may be called only if the transform was successfully initialized before.
