    17 /*

    18   Use these macro like assertions, but they assert properties

    19   on types (usually template arguments). In technical terms they

    20   verify whether a type "models" a "concept".

    21 

    22   This set of requirements and the terminology used here is derived

    23   from the book "Generic Programming and the STL" by Matt Austern

    24   (Addison Wesley). For further information please consult that

    25   book. The requirements also are intended to match the ANSI/ISO C++

    26   standard.

    27 

    28   This file covers the basic concepts and the iterator concepts.

    29   There are several other files that provide the requirements

    30   for the STL containers:

    31     container_concepts.h

    32     sequence_concepts.h

    33     assoc_container_concepts.h

    37   TO DO:

    38     - some issues with regards to concept classification and mutability

    39       including AssociativeContianer -> ForwardContainer

    40       and SortedAssociativeContainer -> ReversibleContainer

    41     - HashedAssociativeContainer

    42     - Allocator

    43     - Function Object Concepts
