org.activiti.engine.repository.ProcessDefinition
An object structure representing an executable process composed of activities and transitions. Business processes are often created with graphical editors that store the process definition in certain file format. These files can be added to a {@link Deployment} artifact, such as for example a Business Archive (.bar)file. At deploy time, the engine will then parse the process definition files to an executable instance of this class, that can be used to start a {@link ProcessInstance}. @author Tom Baeyens @author Joram Barez @author Daniel Meyer
