# 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.
