The TDS Format properties described here apply to:
Property | Type | Meaning |
---|---|---|
Tag | String | Specify the value that is used to identify the object
in a message bit stream. If the object is simple and the Data Element Separation property of the complex type or types in which the object is a child is Tagged Delimited, Tagged Fixed Length, or Tagged Encoded Length, this property must contain a non-empty value. If the object is a complex element and the Data Element Separation property of its parent is Tagged Delimited, Tagged Fixed Length, or Tagged Encoded Length, the property can contain an empty value. The value for this property must be unique for every element in the message set; that is, no two elements in the message set can contain the same value for this property. |
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 further details. |
Property | Type | Meaning |
---|---|---|
Physical Type | Enumerated type | The Physical Type can
be set to Characters and Messaging Standard Alternate. This
property tells the TDS parser whether the data in the message is the normal
TDS character format, or is another alternate form that has a specific messaging
standard such as TLOG. The available values and the default value depend on
both Messaging Standard and
the logical type. If the logical type of the object is dateTime, float, or integer, this property is disabled. If the Messaging Standard property (at the message set level) is set to other than TLOG , the Physical Type property is disabled. If the Messaging Standard property (at the message set level) is set to TLOG and the logical type of the object is set to a Boolean, decimal or string type, the Physical Type property can be set to Characters or Messaging Standard Alternate. |
Length Reference | Enumerated type | Specify the identifier of a sibling Integer object,
the value of which dictates the length of the object in question. The sibling
object must be defined before the current object within the message structure.
