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.

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.
