Dune::BlockVectorWindow< B, A > Class Template Reference

#include <bvector.hh>

Inheritance diagram for Dune::BlockVectorWindow< B, A >:

Dune::block_vector_unmanaged< B, A > Dune::base_array_unmanaged< B, A > List of all members.

Detailed Description

template<class B, class A = ISTLAllocator>
class Dune::BlockVectorWindow< B, A >

BlockVectorWindow adds window manipulation functions to the block_vector_unmanaged template.

This class has no memory management. It assumes that the storage for the entries of the vector is maintained outside of this class.

But you can copy objects of this class and of the base class with reference semantics.

Assignment copies the data, if the format is incopmpatible with the argument an exception is thrown in debug mode.

Error checking: no error checking is provided normally. Setting the compile time switch DUNE_ISTL_WITH_CHECKING enables error checking.
