Constructor Detail

### ComparableObjectItem

    public ComparableObjectItem(java.lang.Comparable x,
                                java.lang.Object y)

  Constructs a new data item.

  Parameters:
    `x` - the x-value (`null` NOT permitted).
    `y` - the y-value (`null` permitted).

Method Detail

### getComparable

    protected java.lang.Comparable getComparable()

  Returns the x-value.

  Returns:
    The x-value (never `null`).

### getObject

    protected java.lang.Object getObject()

  Returns the y-value.

  Returns:
    The y-value (possibly `null`).

### setObject

    protected void setObject(java.lang.Object y)

  Sets the y-value for this data item. Note that there is no corresponding method to change the x-value.

  Parameters:
    `y` - the new y-value (`null` permitted).

### compareTo

    public int compareTo(java.lang.Object o1)

  Returns an integer indicating the order of this object relative to another object.

  For the order we consider only the x-value: negative == "less-than", zero == "equal", positive == "greater-than".

  Specified by:
    `compareTo` in interface `java.lang.Comparable`
  Parameters:
    `o1` - the object being compared to.
  Returns:
    An integer indicating the order of this data pair object relative to another object.

### clone

    public java.lang.Object clone()
                           throws java.lang.CloneNotSupportedException

  Returns a clone of this object.

  Overrides:
    `clone` in class `java.lang.Object`
  Returns:
    A clone.
  Throws:
    `java.lang.CloneNotSupportedException` - not thrown by this class, but subclasses may differ.

### equals

    public boolean equals(java.lang.Object obj)

  Tests if this object is equal to another.

  Overrides:
    `equals` in class `java.lang.Object`
  Parameters:
    `obj` - the object to test against for equality (`null` permitted).
  Returns:
    A boolean.

### hashCode

    public int hashCode()

  Returns a hash code.

  Overrides:
    `hashCode` in class `java.lang.Object`
  Returns:
    A hash code.
