Description

Details

GstImplementsInterface

typedef struct _GstImplementsInterface GstImplementsInterface;

Opaque GstImplementsInterface structure.

gst_element_implements_interface ()

gboolean    gst_element_implements_interface
                                            (GstElement *element,
                                             GType iface_type);

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

element : GstElement to check for the implementation of the interface
iface_type : (final) type of the interface which we want to be implemented
Returns : whether or not the element implements the interface.

gst_implements_interface_cast ()

gpointer    gst_implements_interface_cast   (gpointer from,
                                             GType type);

cast a given object to an interface type, and check whether this interface is supported for this specific instance.

from : the object (any sort) from which to cast to the interface
type : the interface type to cast to
Returns : a gpointer to the interface type

gst_implements_interface_check ()

gboolean    gst_implements_interface_check  (gpointer from,
                                             GType type);

check a given object for an interface implementation, and check whether this interface is supported for this specific instance.

from : the object (any sort) from which to check from for the interface
type : the interface type to check for
Returns : whether or not the object implements the given interface
