Detailed Description

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

CompressedBlockVectorWindow adds window manipulation functions to the compressed_block_vector_unmanaged template.

This class has no memory management. It assumes that the storage for the entries of the vector and its index set 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.
