touches (with strategy)

Checks if two geometries have at least one touching point (tangent - non overlapping)

Synopsis

template<typename Geometry1, typename Geometry2, typename Strategy>
bool touches(Geometry1 const & geometry1, Geometry2 const & geometry2, Strategy const & strategy)

Parameters

Type	Concept	Name	Description
Geometry1 const &	Any type fulfilling a Geometry Concept	geometry1	A model of the specified concept
Geometry2 const &	Any type fulfilling a Geometry Concept	geometry2	A model of the specified concept
Strategy const &	Any type fulfilling a Touches Strategy Concept	strategy	The strategy which will be used for touches calculations

Returns

Returns true if two geometries touch each other

Header

Conformance

The function touches implements function Touches from the OGC Simple Feature Specification.

The version with one parameter is additional and not described in the OGC standard
