validateEnumeration

public static java.lang.String validateEnumeration(java.lang.Object value,
                                                   java.util.List<?> enumerationValues,
                                                   java.util.List<?> invalidValues,

validate if a type to reference is valid

Parameters:

value - the value to reference

enumerationValues - the enumeration values that are currently valid

invalidValues - the list of values that are considered invalid.

isNullValid - flag indicating if the reference is allowed to be null.

enumerationType - the enumeration type being validated

Returns:

an error string based on the validation error. If the new type is valid, a null string is returned.
