Description

org.camunda.bpm.engine

Public API of the Camunda Platform engine. Typical usage of the API starts by the creation of a ProcessEngineConfiguration (typically based on a configuration file), from which a ProcessEngine can be obtained. Through the services obtained from such a ProcessEngine, BPM and workflow operation can be executed: RepositoryService: Manages Deployments RuntimeService: For starting and searching ProcessInstances TaskService: Exposes operations to manage human (standalone) Tasks, such as claiming, completing and assigning tasks IdentityService: Used for managing Users, Groups and the relations between them ManagementService: Exposes engine admin and maintenance operations, which have no relation to the runtime execution of business processes HistoryService: Exposes information about ongoing and past process instances. FormService: Access to form data and rendered forms for starting new process instances and completing tasks.

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