Collapse/Expand Metaconnector Data Types

Since the Collapse/Expand Metaconnector has no external database, it always operates with HCL Enterprise Integrator (HEI) or Domino® Enterprise Connection Services (DECS) data types. For key fields, all HEI or DECS datatypes convert within their class (number, datetime, or stream); in addition, precision and overflow checking are performed as needed. For non-key fields, on Fetch, external single-value data types map to internal multivalue data types, and vice-versa on output. Therefore, an external number class type maps to a number list; a datetime to a datetime list; and text to a text list. Note that binary data types (unformatted BLOB or formatted binary types such as composite) cannot be mapped to multivalue types.
