Class InvokeStaticTag

    java.lang.Object
      org.apache.commons.jelly.TagSupport
          org.apache.commons.jelly.tags.core.InvokeStaticTag

All Implemented Interfaces:
  Tag, ArgTagParent

    public class InvokeStaticTag

extends TagSupport
implements ArgTagParent

A Tag which can invoke a static method on a class, without an instance of the class being needed.

Like the `InvokeTag`, this tag can take a set of arguments using the `ArgTag`.

The following attributes are required:

- var - The variable to assign the return of the method call to
- method - The name of the static method to invoke
- className - The name of the class containing the static method
