ReferenceConstraint

public class ValueConstraint
extends Constraint

A constraint the filters/selects based on the value and/or the parsed dataTypes. A valid constraint MUST define a value OR valid data type. A valid data type is defined as a String that is NOT NULL and NOT empty.

If the collection of data types is null components processing this constraint are encouraged to deduct the data types based on the type of the value.
