Applies 2D affine transformation in XY plane.
Parameters
| transform | The affine transformation to be applied to this geometry. |
|---|
public void copyTo (Geometry dst)
Copies this geometry to another geometry of the same type. The result geometry is an exact copy.
public boolean equals (Object _other)
Returns TRUE when this geometry has exactly same type, properties, and coordinates as the other geometry.
public int getDimension ()
Returns the topological dimension of the geometry object based on the geometry's type.
Returns 0 for point and multipoint.
