man Qstl (Fonctions bibliothèques) - support for Forall, Exists, etc in GNU C++ using STL

NAME

Qstl - support for Forall, Exists, etc in GNU C++ using STL

#include <Qstl.h>

bool AO(iter,container,exprn) /* Forall */

bool EO(iter,container,exprn) /* Exists */

bool E1O(iter,container,exprn) /* Exists a single */

bool CO(iter,container,exprn) /* Count */

These macros implement predicate calculus operations over Standard Template Library (STL) classes. For example:

map<Location,Hatsize,Locationlt> m;

AO(i,m,(*i).Hatsize >= 0)

Note that the macros can be nested or used in any context that requires boolean values.

These macros require GNU C or GNU C++.
