Types

type Type

type Type int

Type enumerates the different topological locations which can occur in a {@link Geometry}. The constants are also used as the row and column indices of DE-9IM {@link IntersectionMatrix}es.

const (
	// Interior is the location value for the interior of a geometry.
	// Also, DE-9IM row index of the interior of the first geometry and column index of
	// the interior of the second geometry.
	Interior Type = iota
	// Boundary is the location value for the boundary of a geometry.
	// Also, DE-9IM row index of the boundary of the first geometry and column index of
	// the boundary of the second geometry.
	Boundary
	// Exterior is the location value for the exterior of a geometry.
	// Also, DE-9IM row index of the exterior of the first geometry and column index of
	// the exterior of the second geometry.
	Exterior
	// None is used for uninitialized location values.
	None

func (Type) String

func (t Type) String() string

func (Type) Symbol

func (t Type) Symbol() rune

Symbol converts the location value to a location symbol, for example, Exterior => 'e' locationValue Returns either 'e', 'b', 'i' or '-'
