Class com.vividsolutions.jts.geom.Geometry

Examples of com.vividsolutions.jts.geom.Geometry.equalsExact()

com.vividsolutions.jts.geom.Geometry.equalsExact()
Returns true if the two Geometrys are exactly equal, up to a specified distance tolerance. Two Geometries are exactly equal within a distance tolerance if and only if:
- they have the same class
- they have the same values for their vertices, within the given tolerance distance, in exactly the same order.
If this and the other Geometrys are composites and any children are not Geometrys, returns false. @param other the Geometry with which to compare this Geometry @parm tolerance distance at or below which two Coordinatesare considered equal @return true if this and the other Geometryare of the same class and have equal internal data.
