Class AbstractVersion

java.lang.Object
  ice.util.AbstractVersion

All Implemented Interfaces:

Comparable

Direct Known Subclasses:

JavaVersion

public abstract class AbstractVersion

extends Object

implements Comparable

This class provides a versioning framework for subsystems requiring versioning that can be represented by an array (of any length) of integers.

Field Summary

protected int[]

_versionParts The various parts of the version spec.

Constructor Summary

protected

AbstractVersion(int[] versionSpec) Constructor referenced by subclasses, passing the concrete version specification

Method Summary

int	compareTo(Object obj) Implement the compareTo method, this provides a full length comparison.
int[]	getParts() Retrieve the individual parts of the internal Version representation.

AbstractVersion

protected AbstractVersion(int[] versionSpec)

Constructor referenced by subclasses, passing the concrete version specification

Parameters:

versionSpec -

Method Detail

getParts

public int[] getParts()

Retrieve the individual parts of the internal Version representation. Mainly used by custom comparitors, but may be accessed by the public as well.

Returns:

a copy of the internal version parts.

compareTo

public int compareTo(Object obj)

Implement the compareTo method, this provides a full length comparison.

Specified by:

compareTo in interface Comparable

Parameters:

obj - The other array

Returns:

-X, 0, +X if the argument is less than, equal to, or greater than this instance

Throws:

ClassCastException - if the other object is not an instance of AbstractVersion

ArrayIndexOutOfBoundsException - if the other object is an AbstractVersion constructed with a different size
