Field types

The FieldBuilder is able to create different field types, see the MsgFieldType enumeration.

These MsgField types always have a body (VAL) and may have a header (TAG, LEN). The example here is a MsgField without a header, it has the body (VAL) without the header (TAG and LEN) subfields.

Length and Value types

Some MsgFields have defined the LEN subfield, for example

LEN VAL
 02 123

or

TAG LEN VAL
 60  02 543

or

LEN TAG VAL
 03  60 543

• Examples of TAG types tag-packer.md
• Examples of LEN types length-packer.md
• Examples of VAL types body-packer.md
