set_query_function

Description:

public void set_query_function (CollectPadsQueryFunction func)

Set the query callback function and user data that will be called after collectpads has received a query originating from one of the collected pads.

If the query being processed is a serialized one, this callback is called with this STREAM_LOCK held, otherwise not. As this lock should be held when calling a number of CollectPads functions, it should be acquired if so (unusually) needed.

MT safe.

Parameters:

this	the collectpads to use
func	the function to set
user_data	user data passed to the function
