State Models and Rules

State models define behaviors relating to a concept during its lifecycle. The TIBCO BusinessEvents rule language is used to define many of these behaviors.

Transitions are containers for rules, which control how each instance changes states and property values.

Entry Actions and Exit Actions

As a concept instance enters a state, it executes the associated entry action. While it is within a state, the state’s transition rules determine if, when, and how it will exit the state. As it exits a state, it executes the associated exit action.

Transition Rules

Transition rules determine when, or if, the transition is taken. If you define a rule for the transition, the transition does not occur until the rule executes successfully. See Transitions.

Timeout Expressions and Actions

States and the overall state model can have timeout expressions and actions. The rule language is used to define timeout expressions and timeout actions as explained in State Model Timeouts and State Timeouts.
