Glib::RefPtr<Gst::MiniObject> | wrap (GstMiniObject* object, bool take_copy=false) |
It is similar to Glib::Object but has no GObject property or signal support.

virtual Gst::MiniObject::~MiniObject | ( | ) | [virtual] |
Gst::MiniObject::MiniObject | ( | const MiniObject& | ) |
A copy constructor.
Please note that copying is actually only supported in sub-classes that define their own custom copy function in the C API such as Gst::Event, Gst::Buffer, etc. otherwise the copy is not successful and a warning is issued.
Glib::RefPtr<Gst::MiniObject> Gst::MiniObject::copy | ( | ) | const |
Creates a copy of the mini-object.
Please note that copying is supported only by sub-classes of Gst::MiniObject such as Gst::Event, Gst::Buffer, etc. that define their own custom copy function in the C API and not directly by Gst::MiniObject, a base class. If used from only a Gst::MiniObject instance and not a sub-class instance the copy is not successful and a warning is issued.
MT safe.
Reimplemented in Gst::Buffer, Gst::Event, Gst::Message, and Gst::Query.
Glib::RefPtr<Gst::MiniObject> Gst::MiniObject::create_writable | ( | ) |
Checks if a mini-object is writable.
If not, a writable copy is made and returned. This gives away the reference to the original mini object, and returns a reference to the new object.
MT safe
Reimplemented in Gst::Buffer, Gst::Event, Gst::Message, and Gst::Query.
bool Gst::MiniObject::flag_is_set | ( | guint | flag | ) | const |
Checks to see if the given flag is set.
flag | The flag to check for. |
guint Gst::MiniObject::get_flags | ( | ) | const |
const GstMiniObject* Gst::MiniObject::gobj | ( | ) | const [inline] |
Provides access to the underlying C GstMiniObject.
Reimplemented in Gst::Buffer, Gst::Event, Gst::Message, and Gst::Query.

GstMiniObject* Gst::MiniObject::gobj | ( | ) | [inline] |

bool Gst::MiniObject::is_writable | ( | ) | const |
Checks if a mini-object is writable.
A mini-object is writable if the reference count is one and the Gst::MINI_OBJECT_FLAG_READONLY flag is not set. Modification of a mini-object should only be done after verifying that it is writable.

MiniObject& Gst::MiniObject::operator= | ( | const MiniObject& | ) |
Assignment operator.
Please note that copying is actually only supported in sub-classes that define their own custom copy function in the C API such as Gst::Event, Gst::Buffer, etc. otherwise the copy is not successful and a warning is issued.
void Gst::MiniObject::reference | ( | ) | const |
