- Use these macro like assertions, but they assert properties
- on types (usually template arguments). In technical terms they
- verify whether a type "models" a "concept".
- This set of requirements and the terminology used here is derived
- from the book "Generic Programming and the STL" by Matt Austern
- (Addison Wesley). For further information please consult that
- book. The requirements also are intended to match the ANSI/ISO C++
- standard.
- This file covers the basic concepts and the iterator concepts.
- There are several other files that provide the requirements
- for the STL containers:
- container_concepts.h
- sequence_concepts.h
- assoc_container_concepts.h
- Jeremy Siek, 1999
- TO DO:
- - some issues with regards to concept classification and mutability
- including AssociativeContianer -> ForwardContainer
- and SortedAssociativeContainer -> ReversibleContainer
- - HashedAssociativeContainer
- - Allocator
- - Function Object Concepts
