Member Function Documentation

Referenced& osg::Referenced::operator= (  Referenced &    )  [inline]

void osg::Referenced::ref (    )  const [inline]

increment the reference count by one, indicating that this object has another pointer which is referencing it.

const int osg::Referenced::referenceCount (    )  const [inline]

return the number pointers currently referencing this object.

void osg::Referenced::unref (    )  const [inline]

decrement the reference count by one, indicating that a pointer to this object is referencing it. If the reference count goes to zero, it is assumed that this object is no longer referenced and is automatically deleted.

void osg::Referenced::unref_nodelete (    )  const [inline]

decrement the reference count by one, indicating that a pointer to this object is referencing it. However, do not delete it, even if ref count goes to 0. Warning, unref_nodelete() should only be called if the user knows exactly who will be resonsible for, one should prefer unref() over unref_nodelete() as the later can lead to memory leaks.
