Description

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.
