Detailed Description

template<typename>
class MGLevelObject< typename >

An array with an object for each level. The purpose of this class is mostly to store objects and allow access by level number, even if the lower levels are not used and therefore have no object at all; this is done by simply shifting the given index by the minimum level we have stored.

In most cases, the objects which are stored on each levels, are either matrices or vectors.

Constructor & Destructor Documentation

template<class Object >
MGLevelObject< Object >::MGLevelObject ( const unsigned int  minlevel = 0,
const unsigned int  maxlevel = 0 
)

Constructor allowing to initialize the number of levels. By default, the object is created empty.

Member Function Documentation

template<class Object >
Object & MGLevelObject< Object >::operator[] ( const unsigned int  level)
template<class Object >
const Object & MGLevelObject< Object >::operator[] ( const unsigned int  level) const

Access object on level level. Constant version.

template<class Object >
void MGLevelObject< Object >::resize ( const unsigned int  new_minlevel,
const unsigned int  new_maxlevel 
)
template<class Object >
MGLevelObject< Object > & MGLevelObject< Object >::operator= ( const double  d)

Call operator = (s) on all objects stored by this object. This is particularly useful for e.g. Object==Vector<T>

template<class Object >
void MGLevelObject< Object >::clear ( )

Call clear on all objects stored by this object. This function is only implemented for some Object classes, e.g. the PreconditionBlockSOR and similar classes.
