Method Detail

get

protected java.lang.Object get()

Gets the value of the value-field of this object. You can override this method in the derived class to improve performance, but it is not strictly necessary.

Node: This method is not intended for public use. The whole idea is that concrete holders publicly reveal their value-field for ease of use.
