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

#ifndef __CONCEPT_CHECKS_H
#define __CONCEPT_CHECKS_H

/*
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

#ifndef __CONCEPT_CHECKS_H
#define __CONCEPT_CHECKS_H

/*
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

/*
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

- some issues with regards to concept classification and mutability
including AssociativeContianer -> ForwardContainer

- HashedAssociativeContainer

#ifndef __CONCEPT_CHECKS_H
#define __CONCEPT_CHECKS_H

/*
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

#ifndef __CONCEPT_CHECKS_H
#define __CONCEPT_CHECKS_H

/*
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

/*
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

Self appointed Thought Controlling others threads he doesn't agree with?
