Detailed Description
template<class B, class A = std::allocator<B>>
class Dune::compressed_base_array_unmanaged< B, A >
class Dune::compressed_base_array_unmanaged< B, A >
A simple array container with non-consecutive index set.
Elements in the array are of type B. This class provides
- iterator access
- const_iterator access
random access in log(n) steps using binary search
- find returning iterator
This container has NO memory management at all, copy constuctor, assignment and destructor are all default.
The constructor is made protected to emphasize that objects are only usably in derived classes.
Error checking: no error checking is provided normally. Setting the compile time switch DUNE_ISTL_WITH_CHECKING enables error checking.
This class is an implementation detail, and should not be used outside of dune-istl.
Member Function Documentation
◆ beforeBegin() [1/2]
template<class B , class A = std::allocator<B>>
|
inline |
- Returns
- an iterator that is positioned before the first entry of the vector.
◆ beforeBegin() [2/2]
template<class B , class A = std::allocator<B>>
|
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>>
|
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>>
|
inline |
- Returns
- an iterator that is positioned before the end iterator of the vector. i.e. at the last element.
