Namespace: GameEngine.Geometry
Class: GameEngine/Geometry/ArcGISGeometry
Since: 1.0.0
Summary
Base class for all classes that represent geometric shapes.
Properties
| Property | Type | Nullable | Readonly | Summary |
|---|---|---|---|---|
No | Yes | The number of dimensions for the geometry. | ||
No | Yes | The extent for the geometry. | ||
No | Yes | True if this geometry contains curve segments; false otherwise. | ||
No | Yes | A value indicating if the geometry has M. | ||
No | Yes | A value indicating if the geometry has Z. | ||
No | Yes | Check if a geometry is empty or not. | ||
Yes | Yes | The spatial reference for the geometry. |
Dimension
ArcGISGeometryDimension Dimension
The number of dimensions for the geometry.
Returns ArcGISGeometryDimension.Unknown if an error occurs.
Extent
ArcGISEnvelope Extent
The extent for the geometry.
The extent for the geometry which is a envelope and contains the same spatial reference as the input geometry.
HasCurves
bool HasCurves
True if this geometry contains curve segments; false otherwise.
ArcGIS software supports polygon and polyline geometries that contain curve segments (where ArcGISSegment.IsCurve is true, sometimes known as true curves or nonlinear segments). Curves may be present in certain types of data - for example Mobile Map Packages (MMPK) or geometry JSON.
If a polygon or polyline geometry contains curve segments, this property returns true. Prior to v100.12, it was not possible to access curve segments, and only ArcGISLineSegment instances would be returned when iterating through the segments in a ArcGISPolygon or ArcGISPolyline object, irrespective of this property.
From v100.12, you can use curve segments when using a ArcGISMultipartBuilder to create or edit polygon and polyline geometries, and also get curve segments when iterating through the segments of existing ArcGISMultipart geometries when this property returns true.
HasM
bool HasM
A value indicating if the geometry has M.
If an error occurs false is returned. M is a vertex value that is stored with the geometry.
HasZ
bool HasZ
A value indicating if the geometry has Z.
If an error occurs false is returned. Z typically represent elevations or heights.
IsEmpty
bool IsEmpty
Check if a geometry is empty or not.
Only check the geometry to see if it is empty. Does not check the spatial reference. Returns true if an error occurs.
SpatialReference
ArcGISSpatialReference SpatialReference
The spatial reference for the geometry.
If the geometry does not have a spatial reference null is returned.
Methods
| Signature | Return Type | Summary |
|---|---|---|
Tests if this object is equal to a second ArcGISGeometry object. | ||
Check if two geometries are equal to within some tolerance. | ||
Creates a geometry from an ArcGIS JSON geometry representation. |
Equals
bool Equals(ArcGISGeometry right)
Tests if this object is equal to a second ArcGISGeometry object.
Since 1.0.0
Arguments
| Name | Type | Summary |
|---|---|---|
right | The second geometry. |
Returns bool
True if the comparison succeeds and the objects are equal, false otherwise.
Equals
bool Equals(ArcGISGeometry right, double tolerance)
Check if two geometries are equal to within some tolerance.
Since 1.0.0
Arguments
| Name | Type | Summary |
|---|---|---|
right | The second geometry. | |
tolerance | The tolerance. |
Returns bool
True if the geometries are equal, within the tolerance, otherwise false.
FromJSON
static ArcGISGeometry FromJSON(string inputJSON, ArcGISSpatialReference spatialReference)
Creates a geometry from an ArcGIS JSON geometry representation.
Since 1.0.0
Arguments
| Name | Type | Summary |
|---|---|---|
input | JSON representation of geometry. | |
spatial | The geometry's spatial reference. |
Returns ArcGISGeometry
Geometry converted from a JSON String.
