This method is used for Objects that might be null. The FieldPS does not have a value, this is used to specify a formal FieldPS that can be used in a simple query to match another FieldPS of this type that has any value. TupleSpaceException Set the value of the FieldPS to be any Serializable. The curent Field may be a Formal Field or an Actual Field. Field f1 is always the Query Field.
Strings are equal then return true.
Because the server may not have any awareness of the represented class, we can handle derived classes. The class names as String values must match exactly. Override this method to change the matching behavior. If the Field does not have a value then return the name of the Class that is the type of the Field. If the Field does have a value then return the string representation of the value of the Field.
