Activiti API, the final interface is Processengine, get to processengine instance, get all the APIs in the Activiti system. The important interfaces are as follows:


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 ();
 

 
The Activiti service framework is as follows
