Detailed Description

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

Extend base_array_unmanaged by functions to manipulate.

This container has *NO* memory management at all,
copy constuctor, assignment and destructor are all default.
A container can be constructed as empty or from a given pointer

and size. This class is used to implement a view into a larger array.

You can copy such an object to a base_array to make a real copy.

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]

iterator Dune::base_array_unmanaged< B, std::allocator< B > >::beforeBegin ( )
inlineinherited
Returns
an iterator that is positioned before the first entry of the vector.

◆ beforeBegin() [2/2]

const_iterator Dune::base_array_unmanaged< B, std::allocator< B > >::beforeBegin ( ) const
inlineinherited
Returns
an iterator that is positioned before the first entry of the vector.

◆ beforeEnd() [1/2]

iterator Dune::base_array_unmanaged< B, std::allocator< B > >::beforeEnd ( )
inlineinherited
Returns
an iterator that is positioned before the end iterator of the vector, i.e. at the last entry.

◆ beforeEnd() [2/2]

const_iterator Dune::base_array_unmanaged< B, std::allocator< B > >::beforeEnd ( ) const
inlineinherited
Returns
an iterator that is positioned before the end iterator of the vector. i.e. at the last element.
