Detailed Description

template<typename Value, bool IsIndexable = is_indexable<Value>::value>
struct boost::geometry::index::detail::equal_to< Value, IsIndexable >

The function object comparing Values.

It compares Geometries using geometry::equals() function. Other types are compared using operator==. The default version handles Values which are Indexables. This template is also specialized for std::pair<T1, T2> and boost::tuple<...>.

Template Parameters

Value	The type of objects which are compared by this function object.
IsIndexable	If true, Values are compared using boost::geometry::equals() functions.

template<typename Value, bool IsIndexable = is_indexable<Value>::value>

typedef bool boost::geometry::index::detail::equal_to< Value, IsIndexable >::result_type

The type of result returned by function object.

Member Function Documentation

template<typename Value, bool IsIndexable = is_indexable<Value>::value>

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

inline

Compare values.

If Value is a Geometry geometry::equals() function is used.

Parameters

l	First value.
r	Second value.

Returns

true if values are equal.
