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 incompatible 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.
