gstreamer.MiniObject is a simple structure that can be used to implement refcounted types.
MiniObject.ref and MiniObject.unref increment and decrement the refcount respectively. When the refcount of a mini-object reaches 0, the dispose function is called first and when this returns TRUE, the free function of the miniobject is called.
A copy can be made with MiniObject.copy.
MiniObject.isWritable will return TRUE when the refcount of the object is exactly 1, meaning the current caller has the only reference to the object. MiniObject.makeWritable will return a writable version of the object, which might be a new copy when the refcount was not 1.
Opaque data can be associated with a gstreamer.MiniObject with MiniObject.setQdata and MiniObject.getQdata. The data is meant to be specific to the particular object and is not automatically copied with MiniObject.copy or similar methods.
Sets our main struct and passes it to the parent class.
A destructor is present on this object, but not explicitly documented in the source.
Creates a copy of the mini-object.
Increase the reference count of the mini-object.
Get the main Gtk struct
This function gets back user data pointers stored via MiniObject.setQdata.
the main Gtk struct as a void*
Initializes a mini-object with the desired type and copy/dispose/free functions.
If mini_object has the LOCKABLE flag set, check if the current EXCLUSIVE lock on object is the only one, this means that changes to the object will not be visible to any other object.
Lock the mini-object with the specified access mode in flags.
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.
This sets an opaque, named pointer on a miniobject. The name is specified through a GQuark (retrieved e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the object with MiniObject.getQdata until the object is disposed. Setting a previously set user data pointer, overrides (frees) the old pointer set, using NULL as pointer essentially removes the data stored.
This function gets back user data pointers stored via MiniObject.setQdata and removes the data from object without invoking its destroy() function (if any was set).
Unlock the mini-object with the specified access mode in flags.
Decreases the reference count of the mini-object, possibly freeing the mini-object.
Adds a weak reference callback to a mini object. Weak references are used for notification when a mini object is finalized. They are called "weak references" because they allow you to safely hold a pointer to the mini object without calling MiniObject.ref (MiniObject.ref adds a strong reference, that is, forces the object to stay alive).
Removes a weak reference callback from a mini object.
Atomically modifies a pointer to point to a new mini-object. The reference count of olddata is decreased and the reference count of newdata is increased.
Replace the current gstreamer.MiniObject pointer to by olddata with NULL and return the old value.
Modifies a pointer to point to a new mini-object. The modification is done atomically. This version is similar to MiniObject.replace except that it does not increase the refcount of newdata and thus takes ownership of newdata.
