Detailed Description

template<class TypeT>
class RWNGRef< TypeT >

RWNGRef handles the case of a reference to an element that may have to be negated. It is used by the RWSkewMat matrix class.

Constructor & Destructor Documentation

template<class TypeT >

RWNGRef< TypeT >::RWNGRef ( TypeT &  x, bool  ng = false  )

inline

Builds a reference to x. The parameter ng indicates if the reference should be negated.

Member Function Documentation

template<class TypeT >

RWNGRef< TypeT >::operator TypeT ( )

inline

This type conversion operator is invoked by the compiler as necessary to return the value referenced by the class for use as a right-side value. It may have to modify the value as necessary (for example, to take its conjugate).

template<class TypeT >

RWNGRef<TypeT>& RWNGRef< TypeT >::operator= ( TypeT  x )

inline

This function changes the value referenced by the class to the value x, after modifying x if necessary (for example, by taking its conjugate). If the reference is supposed to be read-only, a runtime error occurs.
