          org.apache.commons.digester.plugins.strategies.FinderFromDfltResource

    public class FinderFromDfltResource

extends RuleFinder

A rule-finding algorithm which looks for a resource file in the classpath whose name is derived from the plugin class name plus a specified suffix.

If the resource-file is found, then it is expected to define a set of Digester rules in xmlrules format.

Since:
  1.6
