Determines the pairs of geometries from the input geometry arrays that participate in the specified spatial relation.
Relation(SpatialReference SpatialReference, Geometry[] InGeometryArray1, Geometry[] InGeometryArray2, esriGeometryRelationEnum RelationName, string RelationParameter)

Description |
|
SpatialReference |
The spatial reference of the geometries in both input geometry arrays. This cannot be null. |
|
InGeometryArray1 |
The base set of Geometry objects in the relation operation. The relationship between each object in the base set is compared to each object in the comparison set (InGeometryArray2). All geometries in this array must be of the same type and are assumed to be in the coordinate system referenced in SpatialReference. |
|
InGeometryArray2 |
The comparison set of Geometry in the relation operation. All geometries in this array must be of the same type and are assumed to be in the coordinate system reference in SpatialReference. |
|
RelationName |
An esriGeometryRelationEnum to define the type of relation evaluated. |
|
RelationParameter |
If the RelationName
enumeration is "esriGeometryRelationRelation", a Shape Comparison
Language parameter string can be used. The Shape
Comparison Language is based on the Calculus-Based Method (CBM), as described
and defined by Clementini and Felice, but has some extensions specific
to working with vertex-based geometries. Refer to the Shape Comparison Language
documentation for proper syntax and available functionality. |
Return Value
A RelationResult[] object for each geometry pair for with the specified relation is true. The left index is the index of the geometry in the base array (InGeometryArray1). The right index is the index of the geometry in the comparison array (InGeometryArray2). If the specified relation is not true for a geometry pair, no RelationResult objects are returned.
