Using Optional Arguments With the Association Methods

You can use the optional arguments with the association methods to filter the classes and instances that are returned. Each optional parameter value passes its results to the next parameter for filtering until all parameters have been processed.

You can pass values for any one or a combination of the optional parameters. You must enter a value or null for each parameter. The first four parameters are used to filter the classes and instances that are returned:

• assocClass

• resultClass

• resultRole

• role

Only the classes and instances that match the values specified for these parameters are returned. The includeQualifiers, includeClassOrigin, and propertyList parameters filter the information that is included in the classes and instances that are returned.
