------------------------------------
Summary: 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.
