 A Glib::wrap() method for this object.


Detailed Description

Core interface implemented by Gst::Element instances that allows runtime querying of interface availability.

This provides interface functionality on a per-instance basis and not a per-class basis, which is the case for GObject.

static bool Gst::Interface::element_implements ( const Glib::RefPtr<const Gst::Element>&  element,
GType  iface_type 
) [static]

Test whether the given element implements a certain interface of type iface_type, and test whether it is supported for this specific instance.

Parameters:
iface_type (final) type of the interface which we want to be implemented.
Returns:
Whether or not the element implements the interface.

bool  take_copy = false 
) [related]

A Glib::wrap() method for this object.

Parameters:
