ValidationContext

extends Object
java.lang.Object
   ↳ com.google.gdata.model.ValidationContext

Class Overview

Data structure used to accumulate data model validation errors.

would be used as follows: 

   public interface Validatable {
     public static class ValidationContext { ... }
     public boolean validate(ValidationContext vc);
   }

   public class Element implements Validatable { ... }
Then we could eventually reuse the context class and the accumulation model in other places (attribute validation? metadata validation?). In that case, we might want to make the 1st arg of addError more generic (like 'Object relatedTo') or something.

Public Methods

public void addError (Element element, String error)

Add an error by error string. This will register an error in the core gdata domain with an error code of "invalidElement" and the internal reason set to the given error string. For a more useful error message, addError(Element, ErrorContent) should be used instead.

Parameters
element
error

public void addError (Element element, ErrorContent error)

Add a validation error to list.

Parameters
element Element that was found to be invalid
error Error message

public Map<Element, List<ErrorContent>> getErrors ()

Returns
  • map of validation errors

public boolean isValid ()

Returns
  • true if instance data is valid

public String toString ()
