Class JobDeclaration<S,T extends JobEntity>

java.lang.Object

org.camunda.bpm.engine.impl.jobexecutor.JobDeclaration<S,T>

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

EventSubscriptionJobDeclaration, MessageJobDeclaration, TimerDeclarationImpl

public abstract class JobDeclaration<S,T extends JobEntity>
extends Object
implements Serializable

A job declaration is associated with an activity in the process definition graph. It provides data about jobs which are to be created when executing this activity. It also acts as a factory for new Job Instances.

Jobs are of a type T and are created in the context of type S (e.g. an execution or an event subscription). An instance of the context class is handed in when a job is created.
