Member Function Documentation

Element< S, T > & self (    )  [inline, inherited]

Accessor to the real type. This accessor is intended to be used by implementations in this class and derivated MetaElement specializations to obtain a reference to the Element instance with its most derivated type.

const Element< S, T > & self (    )  const [inline, inherited]

Accessor to the real type. This accessor is intended to be used by implementations in this class and derivated MetaElement specializations to obtain a reference to the Element instance with its most derivated type.
