Enum SwiftSubfieldFlags

Namespace

Assembly

Set of flags the define some characteristics for subfields. These flags control how the Subfield() method extracts a subfield.

[Flags]
public enum SwiftSubfieldFlags

Fields

EndsAtCrLf = 16

If this flag is included, then the subfield extraction stops at the first CRLF sequence (represented by a single linefeed '\n' in the field content) that is encountered. The linefeed character is not included in the string returned by Subfield().

EndsAtDoubleSlash = 8

If this flag is included, then the subfield extraction stops at the first double-slash sequence '//' that is encountered. The double-slash is not included in the string returned by Subfield().

It is not useful to combine this flag with EndsAtSlash.

EndsAtSlash = 4

If this flag is included, then the subfield extraction stops at the first slash '/' character that is encountered. The slash character is not included in the string returned by Subfield(). Of course, extraction also stops at the first slash of a double-slash.

FixedLength = 1

If this flag is included, then the extracted field is required to have exactly the requested length. If it falls short, then a SwiftException will be thrown. If this flag is not included, then the requested length is merely a maximum length and the extracted subfield string can be shorter.

In SWIFT syntax tables a fixed length is indicated by an exclamation mark, e.g. "3!a" defines an alphabetic subfield with a length of exactly three characters.

None = 0

No special treatment.

Optional = 2

If this flag is included, then the subfield is optional. Hence, possibly nothing will be extracted and Subfield() returns null. If this is flag is not included, then a SwiftException will be thrown when just an empty subfield could be extracted.

In SWIFT syntax tables optional subfields are defined with square brackets, e.g. "[8!a]" defines an optional alphabetic subfield.

Remarks

Multiple flags can be combined using an arithmetic "or" operation. It is also possible to combine the EndsAtSlash, EndsAtDoubleSlash, and EndsAtCrLf flags if a subfield ends with either of those.
