Implementing Pre-Validation Methods
Once you’ve created a validator class skeleton, if you’re adding pre-validation logic for an attribute, you’ll want to implement the performLimitedPreValidation() method. If you’re adding pre-validation logic for an action, you’ll want to implement both the performFullPreValidation() and performLimitedPreValidation() methods. As mentioned in the previous sections regarding limited pre-validation and full pre-validation, the implementations of these two methods may be identical, or they may differ. The class on the next page contains some skeleton implementations of these methods.
public class MyValidator extends DefaultUIComponentValidator{
@Override
public UIValidationResultSet performFullPreValidation()
(UIValidationKey validationKey,
UIValidationCriteria validationCriteria, Locale
locale) throws WTException {
UIValidationResultSet resultSet =
UIValidationResult.newInstance();
// perform your business logic here
// if you want to enable the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
// UIValidationStatus.ENABLED));
// if you want to disable the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
// UIValidationStatus.DISABLED));
// if you want to hide the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
UIValidationStatus.HIDDEN));
return resultSet;
}
@Override
public UIValidationResultSet performLimitedPreValidation()
(UIValidationKey validationKey,
UIValidationCriteria validationCriteria, Locale
locale) throws WTException {
UIValidationResultSet resultSet =
UIValidationResultSet.newInstance();
// perform your business logic here
// if you want to enable the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
// UIValidationStatus.ENABLED));
// if you want to disable the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
// UIValidationStatus.DISABLED));
// if you want to hide the action/component, do this:
//
resultSet.addResult(UIValidationResult.newInstance(validationKey,
UIValidationStatus.HIDDEN));
return resultSet;
}
}
