Package org.activiti

Public API of the Activiti engine.

Typical usage of the API starts by the creation of a org.activiti.Configuration (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:

ProcessService: Allows the creation of Deployments and the starting of and searching on 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

HistoricDataService
IdentityService	is the service to manage Users and Groups.
Job	represents one job (timer, message, etc.).
JobQuery	builds dynamic queries for Jobs.
ManagementService	is a service for admin and maintenance operations on the process engine.
ProcessDefinition	is an object structure representing an executable process composed of activities and transitions.
ProcessEngine	provides access to all the services that expose the BPM and workflow operations.
ProcessEngineInfo	represents information about the initialization of the process engine.
ProcessInstance	represents one execution of a ProcessDefinition.

Class Summary

DbProcessEngineBuilder	builds a process engine based on a couple of simple properties.
Page	holds the parameters of a page (partial result) for a query.
ProcessEngines	helper for initializing and closing process engines in server environments.

Exception Summary

ActivitiException	runtime exception that is the superclass of all Activiti exceptions.
ActivitiOptimisticLockingException	is thrown when an optimistic locking occurs in the datastore caused by concurrent access of the same data entry.
ActivitiWrongDbException	is thrown when the Activiti engine discovers a mismatch between the database schema version and the engine version.
