Hi folks,
what about adding new rules to digester? In my project I have two rules I can share:
1) AddToMapRule
Ctors: AddToMapRule(int stackPosition, String key) AddToMapRule(Map map, String key)
The rule will peek the top level element of the stack and put it into a map. The map can be provided from the outside or is expected at the given stack position (generated by a previous rule). The key is requested as property from the top level element using the PropertyUtils.
Example:
digester.addObjectCreate("data", HashMap.class);
digester.addSetNext("data", "setItems");
digester.addObjectCreate("data/item", Item.class);
digester.addRule("data/item", new AddToMapRule(1, "id"));
digester.addCallMethod("data/item/id", "setId", 0, new Class[] { Integer.class });
digester.addCallMethod("data/item/origin", "setOrigin", 0);
2) DateFormatterRule
Ctors: DateFormatterRule(DateFormat format)
The rule is used to convert an entry to a Date and push it onto the stack. The rule was not realized as Parameter rule, since the API prohibits the call of peekParams and pushParams (package scope instead of protected). See also Alex' mail about the subject.
i'm a bit confused by this last statement. i think that peekParams and pushParams are public (at least in the CVS version).
Example:
digester.addRule("data/item/time", new DateFormatterRule(new SimpleDateFormat("yyyy/MM/dd hh:mm:ss"));
digester.addSetNext("data/item/time", "setTime");
All of the rules support toString, the logger and have unit tests.
that ticks all my boxes :)
Are you interested and what do I have to do for the donation?
AIUI so long as you own the copyright to these works and they have not been published elsewhere then all you need to do is to post them to this list (probably in a zip or a tar) in an email expressing your intention to donate them to the ASF. (or you could create a enhancement request in bugzilla and attach the code if that's easier.)
