Member Function Documentation

Element< S, T > & self  )  [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 [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.
