New convenience methods for ValueMap
------------------------------------
Key: WICKET-1596
URL: https://issues.apache.org/jira/browse/WICKET-1596
Project: Wicket
Issue Type: Improvement
Components: wicket
Affects Versions: 1.4-M1
Environment: Any
Reporter: Doug Donohoe
Priority: Minor
Fix For: 1.4-M2
Attachments: valuemap.patch
Methods to get values out of PageParameters (aka ValueMap) as first class
Objects (Boolean, Integer, Double, Long, Time, Duration) and to get the same
values as primitives if default values are provided without having to worry
about StringConversion exceptions.
This allows one to do:
Integer id = params.getAsInteger("id")
And not have to worry if id is missing or someone tried to hack the query
string by passing in an non-numeric value. Also, it allows you to check for
null without passing in a default value you hope never occurs in practice.
Also allows you to get Enumerated values as page params.
public enum TestEnum {
one, two, three
}
ValueMap vm = new ValueMap();
vm.put("myenum", "one");
TestEnum test = vm.getAsEnum("myenum", TestEnum.class, TestEnum.three);
I have this code done with test cases and a patch ready. I'll see if I can
upload it after I create this issue.
