MiniObject

Object Hierarchy:

Description:

public abstract class MiniObject

MiniObject is a baseclass like Object, but has been stripped down of features to be fast and small. It offers sub-classing and ref-counting in the same way as Object does. It has no properties and no signal-support though. Last reviewed on 2005-11-23 (0.9.5)

Static methods:

public static void replace (ref MiniObject? oldobj, MiniObject? newobj)
Modifies a pointer to point to a new mini-object. The modification is done atomically, and the reference counts are updated correctly. Either newdata and the value pointed to by olddata may be NULL.

Creation methods:

public MiniObject (Type type)
Creates a new mini-object of the desired type. MT safe

Methods:

public virtual MiniObject copy ()
Creates a copy of the mini-object. MT safe
public virtual void finalize ()
public bool flag_is_set (MiniObjectFlags flag)
public void flag_set (MiniObjectFlags flag)
public void flag_unset (MiniObjectFlags flag)
public bool is_writable ()
Checks if a mini-object is writable. A mini-object is writable if the reference count is one and the READONLY flag is not set. Modification of a mini-object should only be done after verifying that it is writable. MT safe
public void make_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 is writable.
public weak MiniObject ref ()
Increase the reference count of the mini-object. Note that the refcount affects the writeability of mini-object, see is_writable. It is important to note that keeping additional references to GstMiniObject instances can potentially increase the number of memcpy operations in a pipeline, especially if the miniobject is a Buffer.
public void unref ()
Decreases the reference count of the mini-object, possibly freeing the mini-object.
public void weak_ref (MiniObjectWeakNotify notify, void* data)
public void weak_unref (MiniObjectWeakNotify notify, void* data)
