- public class FinderFromDfltClass
- extends RuleFinder
A rule-finding algorithm which looks for a method with a specific name
on a class whose name is derived from the plugin class name.
- Since:
- 1.6
Method Summary |
RuleLoader |
findLoader(Digester digester,
java.lang.Class pluginClass,
java.util.Properties p)
If there exists a class whose name is the plugin class name + the
suffix specified to the constructor, then load that class, locate
the appropriate rules-adding method on that class, and return an
object encapsulating that info. |

- See
findLoader(org.apache.commons.digester.Digester, java.lang.Class, java.util.Properties)
.
FinderFromDfltClass
public FinderFromDfltClass(java.lang.String rulesClassSuffix,
java.lang.String methodName)
- Create a rule-finder which invokes a method on a class whenever
dynamic rules for a plugin need to be loaded. See the findRules
method for more info.
- Parameters:
rulesClassSuffix
- must be non-null.methodName
- may be null.
findLoader
public RuleLoader findLoader(Digester digester,
java.lang.Class pluginClass,
java.util.Properties p)
throws PluginException
- If there exists a class whose name is the plugin class name + the
suffix specified to the constructor, then load that class, locate
the appropriate rules-adding method on that class, and return an
object encapsulating that info.
If there is no such class, then just return null.
The returned object (when non-null) will invoke the target method
on the selected 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.
