Version Tag

A version tag may be declared in either a class or interface. It specifices the version of the component or service (depeding if the tag is included within a class or interface). The presence of a version tag signals to the generation tools that a meta-info description is required. In the case of a class, a Type defintion is created whereas an version tag in an interface will result in the generation of a Service descriptor.

package net.osm;

/**
 * Example of a version declaration defintion.  The service tag is  
 * required in order to generate a <classname>.xservice definition  
 * or <classname>.xinfo type descriptor. 
 *
 * @avalon.service version="1.3"
 */
public interface MyService
{
  ...
}

Generated meta-info when declared within an interface:

<service>
  <version>1.3.0<version>
</service>

Generated meta-info when declared within an class:

<type>
  <info>
    <version>1.3.0<version>
  </info>
</type>
