org.jbpm.workflow.execution
Interface AttributeInstance

All Superinterfaces:: java.io.Serializable

public interface AttributeInstance
extends java.io.Serializable

is a process-variable associated with one process instance. The value can be changed during the execution of the flow in following ways :

field input : In the org.jbpm.workflow.definition.ProcessDefinition, a org.jbpm.workflow.definition.Field associates an attribute with an Activity. When an actor performs that Activity, it has to provide input for the attribute. The value that is provided by the actor is stored in the AttributeInstance.
interaction : In every org.jbpm.workflow.delegation.Interaction-implementation the implementor has read & write access to all AttributeInstances through the org.jbpm.workflow.delegation.InteractionContext.
role association : A special kind of AttributeInstances is the role-attribute-instance. They are specified by the actorName-property in the activity. If an actor performs an activity, the attribute-instance with name actorName is set to the actor.
