Class Lines

java.lang.Object
  |
  +--gshute.geom.Lines

public class Lines
extends java.lang.Object

The Lines class provides static utility methods for comparing and generating descriptive strings for lines.

Field Summary
`protected static java.text.DecimalFormat`	`format` format is the decimal format used to format decimal numbers in the toString(Line2D) method.

Method Summary
`static java.util.Comparator`	`firstXComparator()` Lines.firstXComparator() returns a comparator that compares lines based on their first endpoint x-coordinate.
`static java.util.Comparator`	`firstYComparator()` Lines.firstYComparator() returns a comparator that compares lines based on their first endpoint y-coordinate.
`static java.util.Comparator`	`secondXComparator()` Lines.secondXComparator() returns a comparator that compares lines based on their second endpoint x-coordinate.
`static java.util.Comparator`	`secondYComparator()` Lines.secondYComparator() returns a comparator that compares lines based on their second endpoint y-coordinate.
`protected static int`	`sign(double x)` sign(x) returns -1 if x < 0.0, 0 if x == 0.0, and 1 if x > 0.0.
`static java.lang.String`	`toString(java.awt.geom.Line2D l)` Lines.toString(l) returns a String describing l.
