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 more details. |
Property | Type | Meaning |
---|---|---|
Length | Integer | Specify
the expected length of the object in bytes. This property applies to simple objects and to complex elements with a base type. If this property is not set and the message set property Derive default length from logical type is selected, the default value is derived from any length or maxLength value constraint (schema facet) on the simple type. If you set the Data Element Separation property for the type to Fixed Length or Fixed Length AL3, either this property, or the Length Reference property, must contain a value that is not 0 or NULL. Regardless of the value of the Data Element Separation property, either the Length or Length Reference property must be set. |
Length Reference | Enumerated type | 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.
