package org.camunda.bpm.engine;

/**
 * Provides access to all the services that expose the BPM and workflow operations.
 *
 * 
 * 
 * {@link org.camunda.bpm.engine.RuntimeService}:  Allows the creation of
 * {@link org.camunda.bpm.engine.repository.Deployment}s and the starting of and searching on
 * {@link org.camunda.bpm.engine.runtime.ProcessInstance}s.
 * 
 * {@link org.camunda.bpm.engine.TaskService}:  Exposes operations to manage human
 * (standalone) {@link org.camunda.bpm.engine.task.Task}s, such as claiming, completing and
 * assigning tasks
 * 
 * {@link org.camunda.bpm.engine.IdentityService}:  Used for managing
 * {@link org.camunda.bpm.engine.identity.User}s, {@link org.camunda.bpm.engine.identity.Group}s and
 * the relations between them<
 * 
 * {@link org.camunda.bpm.engine.ManagementService}:  Exposes engine admin and
 * maintenance operations
 *  
 * {@link org.camunda.bpm.engine.HistoryService}:  Service exposing information about
 * ongoing and past process instances.
 *
 * {@link org.camunda.bpm.engine.AuthorizationService}: Service allowing
 * to manage access permissions for users and groups.
 * 
 *
 *
 * Typically, there will be only one central ProcessEngine instance needed in a
 * end-user application. Building a ProcessEngine is done through a
 * {@link ProcessEngineConfiguration} instance and is a costly operation which should be
 * avoided. For that purpose, it is advised to store it in a static field or
 * JNDI location (or something similar). This is a thread-safe object, so no
 * special precautions need to be taken.
