Detailed Description

An MgPoint is a 0-dimensional geometry and represents a single location in coordinate space.

Remarks:
An instance of this class is constructed by calling a non-static MgGeometryFactory::CreatePoint() method and, once constructed, is immutable.
Example (PHP)
The following code shows the construction of a point 
/// $geometryFactory = new MgGeometryFactory();
///
/// // create a coordinate
/// $oordinate = $geometryFactory->CreateCoordinateXY(0,2);
///
/// // create a point
/// $point = $geometryFactory->CreatePoint($coordinate);
///
/// // print out the Agf Text string for the geometry
/// $pointAgfText = $wktReaderWriter->Write($point);
///
/// echo "AGF Text representation of Point: $pointAgfTextn";
///
