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.
