Detailed Description

template<class B, class A = std::allocator<B>>
class Dune::VariableBlockVector< B, A >

A Vector of blocks with different blocksizes.

implements a vector consisting of a number of blocks (to
be given at run-time) which themselves consist of a number
of blocks (also given at run-time) of the given type B.

VariableBlockVector is a container of containers!

Member Typedef Documentation

◆ const_reference

template<class B , class A = std::allocator<B>>
typedef const window_type& Dune::VariableBlockVector< B, A >::const_reference

Export type used for const references to container entries.

Note
This is not B&, but an internal proxy class!

◆ reference

template<class B , class A = std::allocator<B>>
typedef window_type& Dune::VariableBlockVector< B, A >::reference

Export type used for references to container entries.

Note
This is not B&, but an internal proxy class!

◆ value_type

template<class B , class A = std::allocator<B>>
typedef BlockVector<B,A> Dune::VariableBlockVector< B, A >::value_type

Type of the elements of the outer vector, i.e., dynamic vectors of B.

Note that this is not the type referred to by the iterators and random access operators, which return proxy objects.

Constructor & Destructor Documentation

◆ VariableBlockVector() [1/3]

template<class B , class A = std::allocator<B>>
Dune::VariableBlockVector< B, A >::VariableBlockVector ( )
inline

constructor without arguments makes empty vector, object cannot be used yet

◆ VariableBlockVector() [2/3]

template<class B , class A = std::allocator<B>>
Dune::VariableBlockVector< B, A >::VariableBlockVector ( size_type  _nblocks)
inlineexplicit

make vector with given number of blocks, but size of each block is not yet known, object cannot be used yet

◆ VariableBlockVector() [3/3]

template<class B , class A = std::allocator<B>>
Dune::VariableBlockVector< B, A >::VariableBlockVector ( size_type  _nblocks,
size_type  m 
)
inline

make vector with given number of blocks each having a constant size, object is fully usable then.

Parameters
_nblocksNumber of blocks
mNumber of elements in each block

Member Function Documentation

◆ beforeBegin()

template<class B , class A = std::allocator<B>>
Iterator Dune::VariableBlockVector< B, A >::beforeBegin ( ) const
inline
Returns
an iterator that is positioned before the first entry of the vector.

◆ beforeEnd() [1/2]

template<class B , class A = std::allocator<B>>
Iterator Dune::VariableBlockVector< B, A >::beforeEnd ( )
inline
Returns
an iterator that is positioned before the end iterator of the vector, i.e. at the last entry.

◆ beforeEnd() [2/2]

template<class B , class A = std::allocator<B>>
ConstIterator Dune::VariableBlockVector< B, A >::beforeEnd ( ) const
inline
Returns
an iterator that is positioned before the end iterator of the vector. i.e. at the last element.

◆ size()

template<class B , class A = std::allocator<B>>
size_type Dune::VariableBlockVector< B, A >::size ( ) const
inline

Number of blocks in the vector

Returns the same value as method N(), because the vector is dense
