Base is the base class for most EasyAR classes.
Base and its derived classes are disposable. If you need to release memories holding by Base immediately, call Dispose. A derived Base in EasyAR is generally lazy initialized, which means the object is not valid before certain methods are called.
Equals false if the internal object has been destroyed or if there is no internal object; otherwise returns true.
Clears this object. All resources including threads holding by the object will be released.
