Constructor Detail

### DefaultKeyedValue

    public DefaultKeyedValue(java.lang.Comparable key,
                             java.lang.Number value)

  Creates a new (key, value) pair.

Parameters:
  `key` - the key.
  `value` - the value (`null` permitted).

Method Detail

### getKey

    public java.lang.Comparable getKey()

  Returns the key.

  Specified by:
    `getKey` in interface `KeyedValue`
  Returns:
    the key.

### getValue

    public java.lang.Number getValue()

  Returns the value.

  Specified by:
    `getValue` in interface `Value`
  Returns:
    the value.

### setValue

    public void setValue(java.lang.Number value)

  Sets the value.

  Parameters:
    `value` - the value.

### equals

    public boolean equals(java.lang.Object o)

  Tests if this object is equal to another.

  Parameters:
    `o` - the other object.
  Returns:
    A boolean.

### hashCode

    public int hashCode()

  Returns a hash code.

  Returns:
    a hash code.

### clone

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

  Returns a clone. It is assumed that both the key and value are immutable objects, so only the references are cloned, not the objects themselves.

  Returns:
    A clone.
  Throws:
    `java.lang.CloneNotSupportedException` - Not thrown by this class, but subclasses (if any) might.
