Package org.activiti.engine

Public API of the Activiti 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 exection 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.

Exception Summary

Exception	Description
ActivitiClassLoadingException	Runtime exception indicating the requested class was not found or an error occurred while loading the class.
ActivitiException	Runtime exception that is the superclass of all Activiti exceptions.
ActivitiIllegalArgumentException	An exception indicating that an illegal argument has been supplied in an Activiti API-call, an illegal value was configured in the engine's configuration or an illegal value has been supplied or an illegal value is used in a process-definition.
ActivitiObjectNotFoundException	An exception indicating that the object that is required or actioned on does not exist.
