Fields
protected VertexDescription m_description
an object which describes the vertex format of the Geometry.
protected int m_touchFlag
a synchronized integer to track the state of the geometry.
Public Methods
public abstract void applyTransformation (Transformation2D transform)
Applies 2D affine transformation in XY plane.
Parameters
| transform | The affine transformation to be applied to this geometry. |
|---|
public double calculateArea2D ()
Calculates the area of the geometry. If the spatial reference is a Geographic Coordinate System (WGS84) then the 2D area calculation is defined in angular units.
Returns
- A double value representing the 2D area of the geometry.
public double calculateLength2D ()
Calculates the length of the geometry. If the spatial reference is a Geographic
Coordinate System (a system where coordinates are defined using angular units such
as longitude and latitude) then the 2D distance calculation is returned
in angular units. In cases where length must be calculated on a Geographic Coordinate
System consider the using the geodeticLength method in GeometryEngine.
Returns
- A double value representing the 2D length of the geometry.
public abstract void copyTo (Geometry dst)
Copies this geometry to another geometry of the same type. The result geometry is an exact copy.
Throws
| GeometryException | invalid_argument if the geometry is of different type. |
|---|
public abstract int getDimension ()
Returns the topological dimension of the geometry object based on the geometry's type.
Returns 0 for point and multipoint.
Returns 1 for lines and polylines.
Returns 2 for polygons and envelopes
Returns 3 for objects with volume
Returns
- Returns the integer value of the dimension of geometry.
public static int getDimensionFromType (int type)
Returns an integer for this geometry's dimension.
Returns 0 for point and multipoint.
Returns 1 for lines and polylines.
Returns 2 for polygons and envelopes
Returns 3 for objects with volume
Parameters
| type | The integer value from geometry enumeration. You can use the method value() to get at the integer value. |
|---|
Returns
- The integer dimension of this geometry.
public int getStateFlag ()
Returns the state of the geometry. The stateFlag value changes with changes applied to this geometry. This allows the user to keep track of the geometry's state.
Returns
- The state of the geometry.
public abstract Geometry.Type getType ()
Returns the geometry type.
Returns
- Returns the geometry type.
public static boolean isArea (int type)
Indicates if the integer value of the enumeration is an area (dimension 2).
Parameters
| type | The integer value from geometry enumeration. You can use the method value() to get at the integer value. |
|---|
Returns
- TRUE if the geometry is a polygon.
public abstract boolean isEmpty ()
Indicates if the geometry object contains geometric information. IsEmpty returns true when the geometry object does not contain geometric information beyond its original initialization state.
Returns
- boolean Returns true if this geometry is empty.
public static boolean isLinear (int type)
Indicates if the integer value of the enumeration is linear (dimension 1).
Parameters
| type | The integer value from geometry enumeration. You can use the method value() to get at the integer value. |
|---|
Returns
- TRUE if the geometry is a line.
public static boolean isMultiPath (int type)
Indicates if the integer value of the enumeration is a multipath (ie, line or area).
Parameters
| type | The integer value from geometry enumeration. You can use the method value() to get at the integer value. |

|---|
Returns
- TRUE if the geometry has multiple vertices.
public static boolean isPoint (int type)
Indicates if the integer value of the enumeration is a point type (dimension 0).
Parameters
| type | The integer value from geometry enumeration. You can use the method value() to get at the integer value. |
|---|

public abstract void queryEnvelope (Envelope env)
Gets the axis aligned bounding box of the geometry.
Parameters
| env | The envelope to return the result in. |
|---|
public abstract void setEmpty ()
Sets the geometry to its original initialization state by releasing all data referenced by the geometry.
Protected Methods
protected Object _getImpl ()
