Method Detail

validate

public void validate(Object fieldValue)
              throws InvalidFieldValueException

Assert validity of a Field value.

The IntegerValidationRule will validate a fieldValue under the following conditions:

1. If the fieldValue equals null and null is an allowed fieldValue the fieldValue is valid, otherwise null is not allowed and the fieldValue is invalid.
2. If the fieldValue is the wildcard character "*", and no FieldValueOptions class has been defined for the FieldInfo object. Then the fieldValue pattern of "*" is valid. However if a FieldValueOptions class has been defined and the class does not contain "*" the fieldValue pattern is invalid.
3. If the fieldValue is of type String and does not equal the wildcard character, and the fieldValue object does not parse into a valid integer value the fieldValue pattern is invalid.
4. If the fieldValue is not of type String or Integer the fieldValue pattern is invalid.
5. If the FieldInfo object contains a FieldValueOptions class, that class must contain the Integer value. If it does not the FieldValue pattern is invalid.
6. If the FieldInfo object contains a minimum value the integer value must be equal to or greater than that minimum value. If it is not then the fieldValue pattern is invalid.
7. If the FieldInfo object contains a maximum value the integer value must be equal to or less than that maximum value. If it is not then the fieldValue pattern is invalid.
8. If all of these questions have been passed the pattern is valid.
