Method Detail

getScopes

public ORecordHook.SCOPE[] getScopes()

Description copied from interface: ORecordHook.Scoped

Returns the array of scopes this hook interested in. By default, all available scopes are returned, implement/override this method to limit the scopes this hook may participate to lower the number of useless invocations of this hook.

Limiting the hook to proper scopes may give huge performance boost, especially if the hook ORecordHook.onTrigger(TYPE, ORecord) dispatcher implementation is heavy. In extreme cases, you may override the ORecordHook.onTrigger(TYPE, ORecord) to act directly on event ORecordHook.TYPE and exit early, scopes are just a more handy alternative to this.

Specified by:

getScopes in interface ORecordHook.Scoped

Returns:

the scopes of this hook.
