Glen Mazza commented on JSPWIKI-864:
------------------------------------
Could we use this: http://commons.apache.org/proper/commons-validator/ ? I
wouldn't want us to be reinventing the wheel if we can avoid it.
> ValidationManager added to WikiEngine

> Key: JSPWIKI-864
> URL: https://issues.apache.org/jira/browse/JSPWIKI-864
> Project: JSPWiki
> Issue Type: Wish
> Components: Core & storage
> Reporter: David Vittor
> Priority: Minor
>
> Here is another idea. When I write plugins, I spend a lot of time writing
> code to make sure that the parameters passed into the plugins are valid.
> Things such as strings, booleans, numbers, urls, emails addresses, etc.
> I was thinking if we could create a ValidationManager class that could take a
> List of "Validators (interface)" and pass values for validation.
> The two main interface method of a Validator would be:
> * void validate(String value, String type) throws InvalidValueException;
> * void validate(String value, String type, boolean required) throws
> InvalidValueException;
> ** Note: by default "required" would be false.
> The type would be a static int TYPE_EMAIL, TYPE_STRING, etc. defined in the
> ValidationManager.
> The ValidationManager, would have property:
> * List<Validator> validators;
> and methods:
> * void addValidator(Validator v);
> * Validator removeValidator(Validator v);
> * List <Validator> getValidators();
> This would be very beneficial for all plugin developers, cause then they can
> call:
> *
> wikiContent.getValidationManager().validate(params.get('url'),ValidationManager.TYPE_URL);
> And they don't need a try catch, as the user will be told exactly what the
> error was. If all parameters are valid, the plugin can continue to do it's
> work.
