Syntax

public class RectangleIntersects

Remarks

This class works for all input geometries, including GeometryCollections.

As a further optimization, this class can be used in batch style to test many geometries against a single rectangle.

Constructors

RectangleIntersects(Polygon)

Create a new intersects computer for a rectangle.

Declaration

public RectangleIntersects(Polygon rectangle)

Parameters

Type	Name	Description
Polygon	rectangle	A rectangular polygon.

Fields

MaximumScanSegmentCount

Crossover size at which brute-force intersection scanning is slower than indexed intersection detection. Must be determined empirically. Should err on the safe side by making value smaller rather than larger.

Declaration

public const int MaximumScanSegmentCount = 200

Field Value

Type	Description
int

Methods

Intersects(Geometry)

Tests whether the given Geometry intersects the query rectangle.

Declaration

public bool Intersects(Geometry geom)

Parameters

Type	Name	Description
Geometry	geom	The Geometry to test (may be of any type)

Returns

Type	Description
bool	true if an intersection must occur or false if no conclusion about intersection can be made

Intersects(Polygon, Geometry)

Tests whether a rectangle intersects a given geometry.

Declaration

public static bool Intersects(Polygon rectangle, Geometry b)

Parameters

Type	Name	Description
Polygon	rectangle	A rectangular polygon
Geometry	b	A geometry of any kind

Returns

Type	Description
bool	true if the geometries intersect.
