Class GeometryPointEquality

java.lang.Object

org.geolatte.geom.GeometryPointEquality

All Implemented Interfaces:

GeometryEquality

public class GeometryPointEquality
extends java.lang.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.

Constructor and Description
GeometryPointEquality() Constructs an instance that uses ExactPositionEquality to determine whether the Geometrys have the same Positionss.
GeometryPointEquality(PositionEquality pointEq) Constructs an instance that uses the specified PositionEquality to determine whether the Geometrys have the same Positionss.

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.
