Group reference TDS properties

The following tables describe the TDS properties of a group reference.

Field identification

Property Type Meaning
Repeating Element Delimiter String Specify the delimiter that is to be used between repeating elements.

This delimiter is used only when the element repeats and the Data Element Separation property of the parent group or complex type is set to All Elements Delimited or Variable Length Elements Delimited.

A default value is provided if the above conditions are true; if the messaging standard is HL7, the mnemonic <HL7_RS> is used; if the messaging standard is not HL7, and the maximum number of repeats is fixed, the delimiter of the parent group or complex type is used.

If none of the above conditions are true, a default is not applied.

Data Pattern String Specify the regular expression that is to be used by the parser to identify the data in the message to be assigned to the object. This property is used when the Data Element Separation method has been set to Use Data Pattern in the complex type. See Regular expression syntax for more details.

Physical representation

Property Type Meaning
Length Reference Enumerated type This property is applicable only if Physical Type is Text, Binary, or TLOG Specific. If set, this property takes precedence over any value in the Length Units property.

Specify the identifier of a sibling integer object, the value of which determines the length of the object in question. The sibling object must be defined before the current object within the message structure.

For information about reordering elements, see Reordering objects.
