Detailed Description

template<typename Value>
struct boost::geometry::index::equal_to< Value >

The function object comparing Values.

The default version handles Values which are Indexables, std::pair<T1, T2>, boost::tuple<...> and std::tuple<...> if STD tuples and variadic templates are supported. All members are compared from left to right, Geometries using boost::geometry::equals() function, other types using operator==.

Template Parameters

Value

The type of objects which are compared by this function object.

Member Typedef Documentation

template<typename Value >

typedef detail::equal_to<Value>::result_type boost::geometry::index::equal_to< Value >::result_type

Member Function Documentation

template<typename Value >

bool boost::geometry::index::equal_to< Value >::operator() ( Value const &  l, Value const &  r  ) const

inline

Compare Values.

Parameters

l	First value.
r	Second value.

Returns

true if Values are equal.
