Class GeometryPositionEquality

java.lang.Object

org.geolatte.geom.GeometryPositionEquality

All Implemented Interfaces:

GeometryEquality

Direct Known Subclasses:

ApproximateGeometryEquality

public class GeometryPositionEquality
extends Object
implements GeometryEquality

A GeometryEquality that considers two Geometrys to be equal iff one of these conditions is satisfied:

• both have the same type, coordinate reference system and consist of the same Points.
• both are empty

Point equality is determined by the PositionEquality instance that is passed to the constructor. In case of the default no-args constructor, ExactPositionEquality is used.

Method Detail

equals

public <P extends Position> boolean equals(Geometry<P> first,
                                           Geometry<P> second)

Checks whether the first geometry equals the second, for some definition of equality.

Specified by:

equals in interface GeometryEquality

Parameters:

first - a Geometry

second - a second Geometry

Returns:

true if and only if both both Geometrys are equal.
