Field Detail

shell

protected KaboumLinearRing shell

The exterior boundary

holes

protected KaboumLinearRing[] holes

The interior boundaries, if any.

Constructor Detail

KaboumPolygon

public KaboumPolygon(KaboumLinearRing shell)

Constructs a Polygon with the given exterior boundary. The shell and holes must conform to the assertions specified in the OpenGIS Simple Features Specification for SQL.

Parameters:

shell - the outer boundary of the new Polygon. Must be oriented clockwise.

KaboumPolygon

public KaboumPolygon(KaboumLinearRing shell,
                     KaboumLinearRing[] holes)

Constructs a Polygon with the given exterior boundary and interior boundaries.

Parameters:

shell - the outer boundary of the new Polygon. Must be oriented clockwise.

holes - the inner boundaries of the new Polygon. Each must be oriented counterclockwise.
