Struct template hash
boost::hash — A TR1 compliant hash function object.
Synopsis
template<typename T>
struct hash : public std::unary_function<T, std::size_t> {
std::size_t operator()(T const&) const;
};
Description
std::size_t operator()(T const& val) const;
Returns: |
hash_value(val)
|
Notes: |
The call to hash_value
is unqualified, so that custom overloads can be
found via argument dependent lookup.
This is not defined when the macro BOOST_HASH_NO_EXTENSIONS
is defined. The specializations are still defined, so only the specializations
required by TR1 are defined.
|
Throws: |
Only throws if
hash_value(T) throws.
