Class Number

java.lang.Object
  oracle.adfnmc.util.Number

All Implemented Interfaces:

Comparable

Direct Known Subclasses:

Number

public class Number
extends java.lang.Object
implements Comparable

TODO DRM - the java 'Number' class is the abstract supertype of a bunch of numeric types. Since we can't substitute the base classes for these, instead, just have this class encapsulate the numeric types. Also consider tradeoffs off additional class overhead to remove some of the procedural-ness in the xxxValue() methods (ie, make a real Number hierarchy, we have control of construction, so we could do a factory/strategy pattern...)

compareTo

Description copied from interface: Comparable

Answers an integer indicating the relative positions of the receiver and the argument in the natural order of elements of the receiver's class.

Specified by:

compareTo in interface Comparable

Parameters:

obj - Object an object to compare the receiver to

Returns:

int which should be <0 if the receiver should sort before the argument, 0 if the receiver should sort in the same position as the argument, and >0 if the receiver should sort after the argument.

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object
