Class ExpressionMapping<T>

java.lang.Object

ee.telekom.workflow.graph.node.input.ExpressionMapping<T>

All Implemented Interfaces:

InputMapping<T>

public class ExpressionMapping<T>
extends Object
implements InputMapping<T>

InputMapping for a value evaluated by the execution of the given expression.

NB! This is a home-built Expression support class (can be used by implementing the Expression interface), it doesn't have anything to do with the Expression Language support (@see ExpressionLanguageMapping). At the time of writing, this InputMapping is actually not usable via the workflow engine API (DSL).

A possible usage of this class is to dynamically evaluate the delay time of a CatchTimer event node with custom logic based on GraphInstance attribute's (e.g. a client id).
