Detailed Description

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

This container extends base_array_unmanaged by memory management with the usual copy semantics providing the full range of copy constructor, destructor and assignment operators.

You can make
  • empty array
  • array with n components dynamically allocated
  • resize an array with complete loss of data
  • assign/construct from a base_array_window to make a copy of the data

    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]

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.
