All Implemented Interfaces:

java.lang.Cloneable, java.io.Serializable

public class RectangleFuzzySet

extends TrapezoidFuzzySet

implements java.io.Serializable

Used to build specialized FuzzySets that have a rectangle shape. The diagram below shows a RectangleFuzzySet.



Note that the Constructors have been defined to make the generation of such curves as simple as possible. Only 2 points are required to define the rectangle shape.

This is a specialization of the TrapezoidFuzzySet where the left and right shapes are vertical lines (oneLeftX equals zeroLeftX and oneRightX equals zeroRightX).

Constructor Detail

RectangleFuzzySet

public RectangleFuzzySet(double leftX,
                         double rightX)
                  throws XValuesOutOfOrderException

Generate a FuzzySet with an rectangle shape.

Parameters:

leftX - the left x position of the rectangle

rightX - the right x position of the rectangle

Throws:

XValuesOutOfOrderException - if the x values are not in correct increasing order
