The following tables describe the TDS properties of a group reference.
Property | Type | Meaning |
---|---|---|
Data Pattern | String | Specify the regular expression that the parser uses to identify the data in the message to assign to the object. This property is used when the Data Element Separation method is set to Use Data Pattern in the complex type. For more details, see Message Sets: Regular expression syntax. |
Property | Type | Meaning |
---|---|---|
Repeating Element Delimiter | String | Specify the delimiter to use 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 previous 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 previous conditions are true, a default is not applied. |
Repeat reference | Enumerated type | Use this property if the object occurs multiple
times, and the number of occurrences is given dynamically by a field
earlier in the message. Select an integer object from the list of
integer objects that occur before this object in the structure of
the message. The value of the selected integer specifies the number
of occurrences of this object. If no objects are listed, no integer
objects exist before this one in the message structure. If a Repeat Reference is specified, it overrides any setting for the Max Occurs logical property when parsing and writing the message, but not for validating the message. |
