Data types for an unstructured (BLOB) message
A parser is supplied for the body of a message in the BLOB domain; it associates each field with a specific data type.
An unstructured (BLOB) message has the data types shown in the following table.
| Data type of the element | Represented as |
|---|---|
| BLOB | BLOB |
| UnknownParserName | CHARACTER |
If the integration node cannot find a parser that corresponds to the domain that is requested by the user, the message is assigned to the BLOB parser, and the requested domain is preserved in the UnknownParserName field. If a BLOB parser is explicitly created, the UnknownParserName field is still present. It can contain the values of "BLOB" or "none" or can be the zero length string ("").
This information is used by the header integrity routine (described in Parsers) to ensure that the semantic meaning of the message is preserved.
