Method Summary

Modifier and Type	Method and Description
boolean	equals(double[] first, DimensionalFlag firstDF, double[] second, DimensionalFlag secondDF) Tests whether the specified coordinates represent the same point.
boolean	equals(Point first, Point second) Tests whether the specified Points are equal.

Method Detail

equals

boolean equals(Point first,
               Point second)

Tests whether the specified Points are equal.

Parameters:

first - first Point

second - second Point

Returns:

true iff the first is equal to the second Point.

equals

boolean equals(double[] first,
               DimensionalFlag firstDF,
               double[] second,
               DimensionalFlag secondDF)

Tests whether the specified coordinates represent the same point.

The coordinates are assumed to be in the same Coordinate Reference System.

Parameters:

first - the coordinates of the first Point

firstDF - the DimensionalFlag for the first coordinate array

second - the coordinates second Point to test

secondDF - the DimensionalFlag for the second coordinate array

Returns:

true iff the Points represented by the coordinates are equal

Throws:

IllegalArgumentException - when a NULL-argument is passed, or a coordinate array is passed that is smaller than the coordinate dimensions of its corresponding dimensional flag.
