public class MiniObject
extends RefCountedObject

Lightweight base class for the GStreamer object hierarchy MiniObject is a baseclass like GObject, but has been stripped down of features to be fast and small. It offers sub-classing and ref-counting in the same way as GObject does. It has no properties and no signal-support though.

Constructor Detail

MiniObject

public MiniObject(NativeObject.Initializer init)

Creates a new instance of MiniObject

Method Detail

isWritable

public boolean isWritable()

Checks if a mini-object is writable. A mini-object is writable if the reference count is one and the MiniObjectFlags.READONLY flag is not set. Modification of a mini-object should only be done after verifying that it is writable.

Returns:

true if the object is writable.

makeWritable

protected <T extends MiniObject> T makeWritable(Class<T> subclass)

Makes a writable instance of this MiniObject.

The result is cast to subclass.

Parameters:

subclass - the subclass to cast the result to.

Returns:

a writable version of this MiniObject.
