Interface XY_DataSet

public interface XY_DataSet
extends Named, Iterable<Point2D>

A wrapper for 2D double-valued data that provides access to data points via Point2Ds.

Note: Use of the word 'Set' in this class does not imply adherence to the Set interface. An XY_DataGroup may contain multiple identical points, although subclasses are free to provide alternate behavior.

double getClosestY(double x)

Get the Y value for the point with closest X

Parameters:

x -

getClosestX

double getClosestX(double y)

Get the X value for the point with closest Y

Parameters:

y -

set

void set(Point2D point)

Either adds a new DataPoint, or replaces an existing one, within tolerance

set

void set(double x,
         double y)

Creates a new DataPoint, then either adds it if it doesn't exist, or replaces an existing one, within tolerance

set

void set(int index,
         double Y)
  throws IndexOutOfBoundsException

Replaces a DataPoint y-value at the specifed index.

Throws:

IndexOutOfBoundsException

hasPoint

boolean hasPoint(Point2D point)

Determine wheither a point exists in the list, as determined by it's x-value within tolerance. Will return false if given a null value.

hasPoint

boolean hasPoint(double x,
                 double y)

Determine wheither a point exists in the list, as determined by it's x-value within tolerance.

getXValuesIterator

Iterator<Double> getXValuesIterator()

toString

String toString()

Standard java function, usually used for debugging, prints out the state of the list, such as number of points, the value of each point, etc.

Overrides:

toString in class Object

Returns:

value of each point in the function in String format

deepClone

XY_DataSet deepClone()

This function returns a new copy of this list, including copies of all the points. A shallow clone would only create a new DiscretizedFunc instance, but would maintain a reference to the original points.

Since this is a clone, you can modify it without changing the original.
