| FinderSetProperties | | public class FinderSetProperties extends RuleFinder (Code) | | A rule-finding algorithm which expects the user to specify whether
"automatic property setting" is desired. If this class discovers that
this is in fact the case for a declaration, then a RuleLoader is returned
which, when invoked, adds a single SetPropertiesRule instance to the
digester.
This allows ordinary JavaBean classes to be used as plugins, and have
xml attributes be mapped to bean properties of the same name, without
any custom plugin rules being created for them.
This RuleFinder is typically used as the last RuleFinder, so that
automatic property setting only occurs if there is no other source of
custom rules available.

| Method Summary | |
| public RuleLoader | findLoader(Digester d, Class pluginClass, Properties p)
Returns a RuleLoader unless the properties contain an entry
with the name matching constructor param propsAttr, and the value
matching what is in falseval. |
| FinderSetProperties | | public FinderSetProperties(String propsAttr, String falseval)(Code) | | Create a rule-finder which will arrange for a SetPropertiesRule to
be defined for each instance of a plugin, so that xml attributes
map to bean properties.
Param falseval will commonly be the string "false" for config files
written in English.
Parameters:
propsAttr - must be non-null.
Parameters:
falseval - must be non-null. |
| findLoader | | public RuleLoader findLoader(Digester d, Class pluginClass, Properties p)(Code) | | Returns a RuleLoader unless the properties contain an entry
with the name matching constructor param propsAttr, and the value
matching what is in falseval.
If no custom source of rules for a plugin is found, then the user
almost always wants xml attributes to map to java bean properties,
so this is the default behaviour unless the user explicitly indicates
that they do not want a SetPropertiesRule to be provided for
the plugged-in class.
The returned object (when non-null) will add a SetPropertiesRule to
the digester whenever its addRules method is invoked.
