This is a struct used heavily in TooN internals.
They have two main uses. The first use is in construction and is completely hidden. For an expression such as a+b, the return value of operator+ will be constructed in place in the return statement, to prevent excessive copying and calls to new/delete.
The other use is much more visible and is for objects such as TooN::Zeros and TooN::Idendity .
The features allowed (construction, addition, etc) depend on the members present. For simplicity, general arguments are given below. If members are nongeneral, then the operators will simply not be applicable to all vectors or matrices.
Operators belong to any of a number of categories depending on the members they provide. The categories are:
This function must be present for construction and assignment of vectors to work.
Referenced by DiagonalMatrix< Size, Precision, Base >::DiagonalMatrix(), Matrix< Size, Size, Precision >::Matrix(), Operator< Internal::DiagMatrixOp< Size, Precision, Base > >::Operator(), Vector< Vertices, Precision >::operator=(), and Vector< Vertices, Precision >::Vector().
Operator<T> operator()  (  int  size  )  const 
Create an operator that knows its size.
Suitable for vectors and square matrices.
