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 true if two geometries touch each other
Either
#include <boost/geometry.hpp>
Or
#include <boost/geometry/algorithms/touches.hpp>
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
