Method Detail

create

public static ProjectionPoint create(double x,
                                     double y)

Create a ProjectionPoint.

getX

public abstract double getX()

Get the X coordinate

getY

public abstract double getY()

Get the Y coordinate

nearlyEquals

public boolean nearlyEquals(ProjectionPoint other)

Returns the result of nearlyEquals(ProjectionPoint, double), with Misc.defaultMaxRelativeDiffDouble.

nearlyEquals

public boolean nearlyEquals(ProjectionPoint other,
                            double maxRelDiff)

Returns true if this point is nearly equal to other. The "near equality" of points is determined using Misc.nearlyEquals(double, double, double), with the specified maxRelDiff.

Parameters:

other - the other point to check.

maxRelDiff - the maximum relative difference the two points may have.

Returns:

true if this point is nearly equal to other.
