- public class FinderFromMethod
- extends RuleFinder
A rule-finding algorithm which expects the caller to specify a methodname
as a plugin property, where the method exists on the plugin class.
- Since:
- 1.6
Field Summary |
static java.lang.String |
DFLT_METHOD_ATTR
Xml attribute that needs to be present on a plugin declaration
in order to specify the method to load rules from. |
Method Summary |
RuleLoader |
findLoader(Digester d,
java.lang.Class pluginClass,
java.util.Properties p)
If there exists a property with the name matching constructor param
methodAttr, then locate the appropriate Method on the plugin class
and return an object encapsulating that info. |

findLoader
public RuleLoader findLoader(Digester d,
java.lang.Class pluginClass,
java.util.Properties p)
throws PluginException
- If there exists a property with the name matching constructor param
methodAttr, then locate the appropriate Method on the plugin class
and return an object encapsulating that info.
If there is no matching property provided, then just return null.
The returned object (when non-null) will invoke the target method
on the plugin class whenever its addRules method is invoked. The
target method is expected to have the following prototype:
public static void xxxxx(Digester d, String patternPrefix);
- Overrides:
findLoader
in class RuleFinder
- Following copied from class:
org.apache.commons.digester.plugins.RuleFinder
- Throws:
PluginConfigurationException
- if the algorithm finds a source
of rules, but there is something invalid about that source.
