Constructor Detail

LinearRing

public LinearRing(Point[] points)

LinearRing

public LinearRing(String value)
           throws SQLException

This is called to construct a LinearRing from the PostGIS string representation of a ring.

Parameters:

value - Definition of this ring in the PostGIS string format.

Throws:

SQLException - when a SQLException occurs

LinearRing

protected LinearRing(String value,
                     boolean haveM)
              throws SQLException

Parameters:

value - The text representation of this LinearRing

haveM - Hint whether we have a measure. This is given to us by other "parent" Polygon, and is passed further to our parent.

Throws:

SQLException - when a SQLException occurs
