Constructor Detail

MiniObject

protected MiniObject(NativeObject.Initializer init)

Creates a new instance of MiniObject

MiniObject

protected MiniObject(org.freedesktop.gstreamer.MiniObject.Handle handle,
                     boolean needRef)

Method Detail

isWritable

public boolean isWritable()

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.

If the LOCKABLE flag is not set, check if the refcount of mini_object is exactly 1, meaning that no other reference exists to the object and that the object is therefore writable.

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()

Makes a writable instance of this MiniObject.

The result is cast to subclass.

Returns:

a writable version (possibly a duplicate) of this MiniObject.

copy

public <T extends MiniObject> T copy()

Create a new MiniObject as a copy of the this instance.

Returns:

the new MiniObject.

getRefCount

public int getRefCount()
