* Message builder creates a generic message in the form of
|
|
* name: value
|
|
* pairs, in a flat list.
|
|
*
|
|
* The unique part is that the value is typed and for variable-length structures
|
|
* (like a string) a length is included.
|
|
* The effect is that you can fully parse a structure without having any prior knowledge
|
|
* of the fields, the expected content in the fields and the size.
|
|
* You can compare this to an XML stream where some items are stored with tags or attributes
|
|
* are unknown to the reader, without causing any effect on being able to parse them or to write
|
|
* them out again unchanged.
