Detailed Description

definition of the basic hashing functor

This header defines the utilmm::hash functor and some specialization of this one to some standard types.

To define your specialization to a class foo user can do like in the following example :

• file foo.hh

  namespace foo_ns {
    class foo {
      // [...]
    }; // class foo_ns::foo
  }

• file foo.cc

  #include "utilmm/foo.hh"
  #include "utilmm/hash/hash.hh"
  
  size_t utilmm::hash<foo_ns::foo>::operator()(Ty const &x) const {
    // Insert hashing code  here
  }
