Package org.camunda.bpm.engine.delegate

Interfaces used to include Java code in a process as the behavior of an activity or as a listener to process events with JavaDelegates.

Interface Summary

Interface	Description
BaseDelegateExecution
BpmnModelExecutionContext	Implemented by classes which provide access to the BpmnModelInstance and the currently executed FlowElement.
CaseExecutionListener	Listener interface implemented by user code which wants to be notified when a state transition happens on a CaseExecution.
CaseVariableListener	A variable listener can be defined on a scope in a case model.
CmmnModelExecutionContext	Implemented by classes which provide access to the CmmnModelInstance and the currently executed CmmnElement.
DelegateCaseExecution
DelegateCaseVariableInstance
DelegateExecution	Execution used in JavaDelegates and ExecutionListeners.
DelegateListener<T extends BaseDelegateExecution>
DelegateTask
DelegateVariableInstance<T extends BaseDelegateExecution>
DelegateVariableMapping	Represents a delegated mapping of input and output variables.
ExecutionListener	Callback interface to be notified of execution events like starting a process instance, ending an activity instance or taking a transition.
Expression
JavaDelegate	Convience class that should be used when a Java delegation in a BPMN 2.0 process is required (for example, to call custom business logic).
ProcessEngineServicesAware	Interface providing access to the ProcessEngineServices from Java delegation code.
TaskListener	Listener interface implemented by user code which wants to be notified when a property of a task changes.
VariableListener<T extends DelegateVariableInstance<?>>
VariableScope

Exception Summary

Exception	Description
BpmnError	Special exception that can be used to throw a BPMN Error from JavaDelegates and expressions.
