Constructor Detail

OrientedCoordinateArray

public OrientedCoordinateArray(Coordinate[] pts)

Creates a new OrientedCoordinateArray for the given Coordinate array.

Parameters:

pts - the coordinates to orient

Method Detail

orientation

private static boolean orientation(Coordinate[] pts)

Computes the canonical orientation for a coordinate array.

Parameters:

pts - the array to test

Returns:

true if the points are oriented forwards or false

compareTo

public int compareTo(java.lang.Object o1)

Compares two OrientedCoordinateArrays for their relative order

Specified by:

compareTo in interface java.lang.Comparable

Returns:

-1 this one is smaller; 0 the two objects are equal; 1 this one is greater

compareOriented

private static int compareOriented(Coordinate[] pts1,
                                   boolean orientation1,
                                   Coordinate[] pts2,
                                   boolean orientation2)
