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.
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.
Are you interested and what do I have to do for the donation?
Regards,
J�rg
