Class DatabaseConstraintValidator

java.lang.Object
  org.jarbframework.validation.DatabaseConstraintValidator

public class DatabaseConstraintValidator
extends Object

Validates the property values of a bean satisfy our database constraints. Performed database checks include:

• Not nullable columns cannot have null values, unless they are generated
• Column length can never be exceeded. (char and number based)
• Fraction length in number column cannot be exceeded

Whenever a database constraint is violated, a constraint violation will be added for that property. Multiple constraint violations can occur, even on the same property.
