unsigned int | minlevel |
std::vector < std_cxx1x::shared_ptr < Object > > | objects |
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.
MGLevelObject< Object >::MGLevelObject | ( | const unsigned int | minlevel = 0 , |
|
const unsigned int | maxlevel = 0 | |||
) | [inline] |
Constructor allowing to initialize the number of levels. By default, the object is created empty.

Object & MGLevelObject< Object >::operator[] | ( | const unsigned int | level | ) | [inline] |
Access object on level level
.

const Object & MGLevelObject< Object >::operator[] | ( | const unsigned int | level | ) | const [inline] |

void MGLevelObject< Object >::resize | ( | const unsigned int | new_minlevel, | |
const unsigned int | new_maxlevel | |||
) | [inline] |
Delete all previous contents of this object and reset its size according to the values of new_minlevel
and new_maxlevel
.

MGLevelObject< Object > & MGLevelObject< Object >::operator= | ( | const double | d | ) | [inline] |
Call operator = (s)
on all objects stored by this object. This is particularly useful for e.g. Object==Vector<T>
References MGLevelObject< Object >::objects.
void MGLevelObject< Object >::clear | ( | ) | [inline] |
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.
