IPointIDAware Interface

Indicator interface that identifies geometries that can have persistent point ID values attached to coordinates.

Description

Indentifies objects that can have and use PointIDs. An object will only use its PointID attributes if it is set to be Aware of them.

Members

	Name	Description
	DropPointIDs	Unsets all PointID values without changing awareness. Only works if geometry is aware of PointIDs.
	PointIDAware	Indicates whether or not the geometry is aware of and capable of handling PointIDs.
	PointIDSimple	Indicates if all PointID values for this geometry are well-defined. Only works if geometry is aware of PointIDs.

IPointIDAware.DropPointIDs Method

Unsets all PointID values without changing awareness. Only works if geometry is aware of PointIDs.

Public Sub DropPointIDs ( _
)

public void DropPointIDs (
);

Description

Resets all PointID values to there initial value of 0. PointIDAware does not change.

IPointIDAware.PointIDAware Property

Indicates whether or not the geometry is aware of and capable of handling PointIDs.

Public Property PointIDAware As Boolean

public bool PointIDAware {get; set;}

Description

Returns or sets the PointID Awareness state of the geometry object. If PointIDAware is TRUE, then the object will recognize that it has PointID attributes and perform operations on them as necessary. If PointIDAware is FALSE, the object will ignore PointIDs while performing operations.

IPointIDAware.PointIDSimple Property

Indicates if all PointID values for this geometry are well-defined. Only works if geometry is aware of PointIDs.

Public ReadOnly Property PointIDSimple As Boolean

public bool PointIDSimple {get;}

Description

PointIDSimple is TRUE when all of the PointIDs are well defined (not equal to 0). If any PointIDs equal 0, PointIDSimple is FALSE.
