Class ValidationErrors

java.lang.Object
  org.srplib.validation.ValidationErrors

public class ValidationErrors
extends Object

Validation error collector object.

Is used by binding code to collect validation errors.

Normally ValidationErrors is created by auto-binding code, but it can be created implicitly by throwing validation exception:

  throw new ValidationException("error message");
  throw new ValidationException(Validators.newError("Error message", formField));
 

or explicitly:

  ValidationErrors validationErrors = new ValidationErrors();
  ...
  validationErrors.add(ValidationError.newError("Value should be positive.", ageField))
  ...
  if (validationErrorCollector.hasErrors()) {
      // take some action
  }
