Listener Required Signature
Simple listeners (callback functions) must have a signature with the parameter types except the opaque parameter. The advanced listener also uses the opaque parameter.
See Pattern Matching Functions in a Project to understand how these parameter values are created.
| Parameter | Notes |
|---|---|
| String patternDefURI | Identifies the URI of the registered pattern definition. |
| String patternInstanceName | The name of the instantiated pattern instance.
This name enables you to identify data belonging to different instantiations of the registered pattern definitions. |
| Object correlationId | This ID is derived from the first correlation property for each pattern set. The success or failure rule function is executed once for each set. |
| Object closure | Closure object provided when executing the
Pattern.Manager.setClosure() function.
The closure for a pattern is used to distinguish one instantiated pattern instance from another, generally used in completion and failure listeners. |
| Object opaque | Provides some insight into the events that triggered the pattern, using provided catalog functions. |
