Detailed Description
class Dune::block_vector_unmanaged< B, A >
An unmanaged vector of blocks.
block_vector_unmanaged extends the 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.

- 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.
