The version Element
From Documentation
Syntax:
<version> <version-class>a_class</version-class> <version-uuid>a_version</version-uuid> <zk-version>a_version</zk-version> </version>
[Optional]
It specifies the version of this configuration. It also controls whether to ignore this configuration.
First, ZK checks if the specified class (<version-calss>) matches the version (<version-uuid>). Second, it checks if ZK's version is the same or larger than the version specified in <zk-version>.
The specified class, if any, must have a static field called UID
. ZK will compare its value with the version specified in <version-uuid>. For example,
package foo;
public class MyAddon {
public static public static final String UID = "1.0.3";
}
Then, you could specify it as follows.
<version>
<version-class>foo.MyAddon</version-class>
<version-uid>1.0.3</version-uid>
<zk-version>5.0.0</zk-version>
</version>
which means foo.MyAddon.UID
must be 1.0.3, and WebApp.getVersion() must be 5.0.0 or later.
