Detailed Description

template<integer dims, class NT = NumericTraits<number,dims>> class MODEL::NormFunction

Takes a vectorfunction and returns its norm instead

Definition at line 29 of file normfunction.h.

Constructor & Destructor Documentation

NormFunction ( vf & vfu, bool own = false, numT scale = 1.0 ) [inline]

Contructor which takes a copy Parameters: own   tells the const. if it is OK to take a copy scale   scales the norm (handy in some cases) Definition at line 38 of file normfunction.h. Referenced by clone().

NormFunction ( const NormFunction<dims, NT> & vfu ) [inline]

Copy constructor. Design decision: a copy off a Normfunction is NEVER owned (which is sort of logical, as we cannot access the original anymore anyway - no accessor for the moment) Definition at line 44 of file normfunction.h.

Member Function Documentation

NormFunction * clone ( void ) const [inline, virtual]

Virtual Copy Constructor Reimplemented from MODEL::ScalarFunction. Definition at line 64 of file normfunction.h.

const numT & function ( numT & fu, const vect & u ) [inline, virtual]

Implement this function to create the return vector. fu is a reference to where the values should be stored. This is for efficiency in internal routines. Inherited classes should return fu too. Reimplemented from MODEL::ScalarFunction. Definition at line 72 of file normfunction.h.

const vect & function_value ( void ) [inline]

Return the value of the function during the last call Definition at line 77 of file normfunction.h.

const NormFunction & operator= ( const NormFunction<dims, NT> & vfu ) [inline]

Assignment operator. Actually not sure if this is useful. Same strategy applies as for copy constructor Definition at line 50 of file normfunction.h.

Member Data Documentation

vect values [private]

Keeps the result of the last function call, so we do not have to call the function twice to get the values and the norm Definition at line 85 of file normfunction.h.
