Package org.camunda.bpm.engine.cdi.impl

Class ProcessVariableMap

java.lang.Object

org.camunda.bpm.engine.cdi.impl.ProcessVariableMap

All Implemented Interfaces:

java.util.Map<java.lang.String,java.lang.Object>, VariableMap

public class ProcessVariableMap
extends java.lang.Object

Allows to expose the process variables of the current business process as a java.util.Map

The map delegates changes to BusinessProcess.setVariable(String, Object) and BusinessProcess.getVariable(String), so that they are not flushed prematurely.
