Iv. Main Service Code

Repositoryservice: Provides methods for obtaining information about various processes and deployment files.

Taskservice: Provides various actions related to the task

Identityservice: Manage users and user groups.

Formservice: Gets or binds data to the process instance

Runtimeservice: Provides methods for manipulating deployment files, process files, and process instances.

Managementservice: Provides administrator monitoring of the process engine, regardless of the process Engine service application.

Historyservice: Provides various process instance information that is being executed and executed in the past

Processengine processengine = Processengines.getdefaultprocessengine ();  Runtimeservice Runtimeservice = Processengine.getruntimeservice ();  Repositoryservice Repositoryservice = Processengine.getrepositoryservice ();  Taskservice Taskservice = Processengine.gettaskservice ();  Managementservice Managementservice = Processengine.getmanagementservice ();  Identityservice Identityservice = Processengine.getidentityservice ();  Historyservice Historyservice = Processengine.gethistoryservice ();  Formservice Formservice = Processengine.getformservice ();
