Declaration

protected GraphComponent(Label label)

Parameters

Type	Name	Description
Label	label

Properties

Coordinate

Declaration

public abstract Coordinate Coordinate { get; protected set; }

Property Value

Type	Description
Coordinate	A coordinate in this component (or null, if there are none).

Covered

Declaration

public bool Covered { get; set; }

Property Value

Type	Description
bool

InResult

Declaration

public bool InResult { get; set; }

Property Value

Type	Description
bool

IsCovered

Declaration

public bool IsCovered { get; }

Property Value

Type	Description
bool

IsCoveredSet

Declaration

public bool IsCoveredSet { get; }

Property Value

Type	Description
bool

IsInResult

IsInResult indicates if this component has already been included in the result.

Declaration

public bool IsInResult { get; }

Property Value

Type	Description
bool

IsIsolated

An isolated component is one that does not intersect or touch any other component. This is the case if the label has valid locations for only a single Geometry.

Declaration

public abstract bool IsIsolated { get; }

Property Value

Type	Description
bool	true if this component is isolated.

IsVisited

Declaration

public bool IsVisited { get; }

Property Value

Type	Description
bool

Label

public Label Label { get; protected set; }

Property Value

Type	Description
Label

Visited

Declaration

public bool Visited { get; set; }

bool

Methods

ComputeIM(IntersectionMatrix)

Compute the contribution to an IM for this component.

Declaration

public abstract void ComputeIM(IntersectionMatrix im)

Parameters

Type	Name	Description
IntersectionMatrix	im	An IntersectionMatrix

UpdateIM(IntersectionMatrix)

Update the IM with the contribution for this component. A component only contributes if it has a labelling for both parent geometries.

Declaration

public void UpdateIM(IntersectionMatrix im)

Parameters

Type	Name	Description
IntersectionMatrix	im	An IntersectionMatrix
