Interface ProcessEngine

public interface ProcessEngine

provides access to all the services that expose the BPM and workflow operations.

• 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

Typically, there will be only one central ProcessEngine instance needed in a end-user application. Building a ProcessEngine is done through a DbProcessEngineBuilder 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.
