Package org.camunda.bpm.engine Description

Public API of the Activiti engine.

Typical usage of the API starts by the creation of a org.activiti.engine.ProcessEngineConfiguration (typically based on a configuration file), from which a org.activiti.engine.ProcessEngine can be obtained.

Through the services obtained from such a org.activiti.engine.ProcessEngine, BPM and workflow operation can be executed:

org.activiti.engine.RepositoryService: Manages org.activiti.engine.repository.Deployments
org.activiti.engine.RuntimeService: For starting and searching org.activiti.engine.runtime.ProcessInstances
org.activiti.engine.TaskService: Exposes operations to manage human (standalone) org.activiti.engine.task.Tasks, such as claiming, completing and assigning tasks
org.activiti.engine.IdentityService: Used for managing org.activiti.engine.identity.Users, org.activiti.engine.identity.Groups and the relations between them
org.activiti.engine.ManagementService: Exposes engine admin and maintenance operations, which have no relation to the runtime exection of business processes
org.activiti.engine.HistoryService: Exposes information about ongoing and past process instances.
org.activiti.engine.FormService: Access to form data and rendered forms for starting new process instances and completing tasks.
