OrRule

Validation rule that allows you to check combinations of rules created with OR logical operations.

Implements: IValidationRule

Description

The OrRule class allows you to validate combinations of rules created with OR logical operations.

Important points

  • When all combined rules return errors, then this rule returns all the errors.

Constructors

Creates a new validation rule and sets its values.

public OrRule(IValidationRule… rules)

Instance methods

validate

public void validate(String path, Schema schema, Object value, List<ValidationResult> results)

  • path: String - dot notation path to the value.
  • schema: Schema - schema this rule is called from.
  • value: Object - value to be validated.
  • results: List<ValidationResult> - list with validation results.

Examples

{@code
  Schema schema = new Schema()
       .withRule(new OrRule(
           new ValueComparisonRule("LT", 1),
           new ValueComparisonRule("GT", 10)
       ));
 
  schema.validate(0);          // Result: no error
  schema.validate(5);          // Result: 5 must be less than 1 or 5 must be more than 10
  schema.validate(20);         // Result: no error
  }
