Description

ECF

Determines whether an action or assignment must take place for the event under analysis

For example, a Refine rule can use either the confirm_external or get_external primitives to execute an external program in response to an event.

Note

You can use a variable to trigger an ECF event and call in the action clauses that follow. For more information about variables in rules, see Variables in rules.

The following figure shows the syntax of an event condition formula (ECF) definition for a Refine rule:
