Class Version

java.lang.Object
  org.deegree.commons.tom.ows.Version

All Implemented Interfaces:

java.lang.Comparable<Version>

public class Version
extends java.lang.Object
implements java.lang.Comparable<Version>

Version of an OWS operation or specification. Comparability of Version objects simplifies tasks like version negotiation.

Description from owsCommon.xsd, version 1.1.0: The string value shall contain one x.y.z "version" value (e.g., "2.1.3"). A version number shall contain three non-negative integers separated by decimal points, in the form "x.y.z". The integers y and z shall not exceed 99.

Each version shall be for the Implementation Specification (document) and the associated XML Schemas to which requested operations will conform. An Implementation Specification version normally specifies XML Schemas against which an XML encoded operation response must conform and should be validated.

               int z)
        throws InvalidParameterValueException

Constructs a Version for an OWS operation.

Parameters:

x - major version. Must be a positive integer.

y - minor version. Must be between 0 and 99.

z - minor sub version. Must be between 0 and 99.

Throws:

The string value shall contain one x.y.z "version" value (e.g., "2.1.3"). A version number shall contain three non-negative integers separated by decimal points, in the form "x.y.z". The integers y and z shall not exceed 99.

Parameters:

s - a String containing the Version representation to be parsed

Returns:

a corresponding Version object

Throws:

InvalidParameterValueException - if the string does not contain a parsable Version
