Detailed Description
template<class B, class A = std::allocator<B>>
class Dune::compressed_block_vector_unmanaged< B, A >
class Dune::compressed_block_vector_unmanaged< B, A >
compressed_block_vector_unmanaged extends the compressed base_array_unmanaged by vector operations such as addition and scalar multiplication. No memory management is added.
Error checking: no error checking is provided normally. Setting the compile time switch DUNE_ISTL_WITH_CHECKING enables error checking.
Member Function Documentation
◆ beforeBegin() [1/2]
|
inlineinherited |
- Returns
- an iterator that is positioned before the first entry of the vector.
◆ beforeBegin() [2/2]
|
inlineinherited |
- Returns
- an iterator that is positioned before the first entry of the vector.
◆ beforeEnd() [1/2]
|
inlineinherited |
- Returns
- an iterator that is positioned before the end iterator of the vector, i.e. at the last entry.
◆ beforeEnd() [2/2]
|
inlineinherited |
- Returns
- an iterator that is positioned before the end iterator of the vector. i.e. at the last element.
