HasProperInteriorIntersection

A proper interior intersection is a proper intersection which is not contained in the set of boundary nodes set for this SegmentIntersector.

Declaration

public bool HasProperInteriorIntersection { get; }

Property Value

Type	Description
bool	Indicates a proper interior intersection

HasProperIntersection

A proper intersection is an intersection which is interior to at least two line segments. Note that a proper intersection is not necessarily in the interior of the entire Geometry, since another edge may have an endpoint equal to the intersection, which according to SFS semantics can result in the point being on the Boundary of the Geometry.

Declaration

public bool HasProperIntersection { get; }

Property Value

Type	Description
bool	Indicates a proper intersection with an interior to at least two line segments

IsDone

Gets a value indicating that the segment intersector is finished.

Declaration

public bool IsDone { get; }

Property Value

Type	Description
bool

Remarks

Always returns false

IsDoneIfProperInt

Sets a flag if the segment intersector is done when a proper intersection has been found.

Declaration

[Obsolete("Not used anymore, will be removed in a later version")]
public bool IsDoneIfProperInt { set; }

Property Value

Type	Description
bool

Remarks

Has no effect anymore.

ProperIntersectionPoint

Declaration

public Coordinate ProperIntersectionPoint { get; }

Property Value

Type	Description
Coordinate	The proper intersection point, or `null` if none was found.

Methods

AddIntersections(Edge, int, Edge, int)

This method is called by clients of the EdgeIntersector class to test for and add intersections for two segments of the edges being intersected. Note that clients (such as MonotoneChainEdges) may choose not to intersect certain pairs of segments for efficiency reasons.

Declaration

public void AddIntersections(Edge e0, int segIndex0, Edge e1, int segIndex1)

Parameters

Type	Name	Description
Edge	e0
int	segIndex0
Edge	e1
int	segIndex1

Declaration

public static bool IsAdjacentSegments(int i1, int i2)

Parameters

Type	Name	Description
int	i1
int	i2

Returns

Type	Description
bool
