org.jbpm.graph.node
Class Fork

java.lang.Object
  org.jbpm.graph.def.GraphElement
      org.jbpm.graph.def.Node
          org.jbpm.graph.node.Fork

All Implemented Interfaces:

java.io.Serializable, Parsable

---

public class Fork
extends Node
implements Parsable

specifies configurable fork behaviour.

if this fork behaviour is not sufficient for your needs, consider writing your own custom TokenHandler.

this forkhandler can be configured in 3 ways :

• without configuration : in that case the fork will launch one new sub-token over each of the leaving tranisions of the fork node.
• a script : can be used to calculate a collection of transition names at runtime. if a script is configured, the script must have exactly one variable with 'write' access. that variable should be assigned a java.util.Collection in the script expression.
