ProcessEngine (Camunda Platform Javadocs 7.19.15-ee)

All Superinterfaces:

ProcessEngineServices

All Known Implementing Classes:

ProcessEngineImpl
```
public interface ProcessEngine
extends ProcessEngineServices
```
Provides access to all the services that expose the BPM and workflow operations.
- RuntimeService: 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
- HistoryService: Service exposing information about ongoing and past process instances.
- 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 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.
