Detailed Description

template<class Object>
class MGLevelObject< Object >

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

MGLevelObject()

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

operator[]() [1/2]

template<class Object >

Object & MGLevelObject< Object >::operator[]

(

const unsigned int

level

)

Access object on level level.

Definition at line 124 of file mg_level_object.h.

operator[]() [2/2]

template<class Object >

const Object & MGLevelObject< Object >::operator[]

(

const unsigned int

level

)

const

Access object on level level. Constant version.

Definition at line 134 of file mg_level_object.h.

resize()

template<class Object >

void MGLevelObject< Object >::resize	(	const unsigned int	new_minlevel,
		const unsigned int	new_maxlevel
	)

Delete all previous contents of this object and reset its size according to the values of new_minlevel and new_maxlevel.

Definition at line 144 of file mg_level_object.h.

operator=()

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>

Definition at line 162 of file mg_level_object.h.

clear()

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.

Definition at line 173 of file mg_level_object.h.

min_level()

template<class Object >

unsigned int MGLevelObject< Object >::min_level

(

)

const

Coarsest level for multigrid.

Definition at line 183 of file mg_level_object.h.

max_level()

template<class Object >

unsigned int MGLevelObject< Object >::max_level

(

)

const

Finest level for multigrid.

Definition at line 191 of file mg_level_object.h.

memory_consumption()

template<class Object >

std::size_t MGLevelObject< Object >::memory_consumption

(

)

const

Memory used by this object.

Definition at line 199 of file mg_level_object.h.

Member Data Documentation

minlevel

template<class Object>

unsigned int MGLevelObject< Object >::minlevel

private

Level of first component.

Definition at line 100 of file mg_level_object.h.

objects

template<class Object>

std::vector<std_cxx11::shared_ptr<Object> > MGLevelObject< Object >::objects

private

Array of the objects to be held.
