Member Function Documentation

GenericValue CGRS::CallbackObjectValue::invokeOnInterface	(	in string	interfaceName,
		in string	methodName,
		in ValueSequence	inValues,
		out ValueSequence	outValues,
		out boolean	wasException
	)

Called to attempt to invoke a user-implemented operation on an object.

The user should at least implement query_interface on XPCOM::IObject, and all required operations and attributes for the supported interfaces. There is no need to implement add_ref and release_ref via invokeOnInterface; such calls will be directed to the CallbackObjectValue object directly rather than via generics.

Parameters

interfaceName	The name of the interface on which to invoke the operation.
methodName	The name of the method to invoke. get is prefixed for attribute getters; set is prefixed for attribute setters.
inValues	The values of the in and in/out parameters to invoke the method with.
outValues	The values of the out and in/out parameters returned from the method.
wasException	If this out parameter comes back true, an exception was raised. In this case, the size and generic type of outValues and the return value are undefined.

Returns

A GenericValue representing the return value.
