Class GJXYSeries

java.lang.Object

kcl.waterloo.graphics.data.GJXYSeries

public class GJXYSeries
extends java.lang.Object

Class for representing paired x,y data as ArrayList lists of equal length. The x, y data are immutable - getX() and getY() methods return copies. There is no public null constructor. To serialize this class to XML with the beans encoder, define a custom persistence delegate, e.g.: <@code xmlencoder.setPersistenceDelegate(GJXYSeries.class, new DefaultPersistenceDelegate(new String[]{"x", "y"}));>

Constructor Detail

GJXYSeries

public GJXYSeries(java.util.ArrayList<java.lang.Double> x,
          java.util.ArrayList<java.lang.Double> y)

Set x and y. These are copied by reference so the capacity to maintain an external reference to the ArrayLists is preserved if that is needed. To avoid that, provide a temporary copy of the ArrayLists as input. Asserts ArrayIndexOutOfBoundsException if x and y are not the same size.

Parameters:

x - ArrayList copied by reference from the input

y - ArrayList copied by reference from the input

GJXYSeries

public GJXYSeries(java.util.ArrayList<java.util.ArrayList<java.lang.Double>> xy)

GJXYSeries

public GJXYSeries(java.lang.Double[] x,
          java.lang.Double[] y)

Creates an instance by forming ArrayLists from the inputs.

Parameters:

x - Double[]

y - Double[]

GJXYSeries

public GJXYSeries(double[] x,
          double[] y)

Creates an instance by forming ArrayLists from the inputs.

Parameters:

x - double[]

y - double[]
