Detailed Description

template<class TypeT>
class RWROCJRef< TypeT >

RWROCJRef<T> handles a reference to a datum that may be read-only, or may need to be conjugated. It is used by the RWHermBandMat<T> classes. Elements outside the band are defined as 0. Accessing these elements returns an RWROCJRef<T> initialized with a static variable initialized to 0, and information that the reference is read-only.

Constructor & Destructor Documentation

template<class TypeT >

RWROCJRef< TypeT >::RWROCJRef	(	TypeT &	x,
		bool	ro = false,
		bool	cj = false
	)			[inline]

Builds a reference to x. The parameter ro indicates if the reference should be considered read-only. The parameter cj indicates if the reference should be conjugated.

Member Function Documentation

template<class TypeT >

RWROCJRef< 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 >

RWROCJRef<TypeT>& RWROCJRef< 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.
