The query is sent to all pads internally linked to this. Note that if there are many possible sink pads that are internally linked to this, only one will be sent the query. Multi-sinkpad elements should implement custom query handlers.

parent	the parent of this or `null`
query	the Query to handle.

Returns:

true if the query was performed successfully.
