Detailed Description

A sub-class of Message that makes it more clear that this Message object only exists as a chunk of data.

RTTI can help us determine this rather than checking Message::typ, and it makes the code a little more clear, I think.

Note:

Is this really true? Or would it be better just to use Message in it's natural form for this? Does the subclassing make either the clarity of code enough better/easier that this is worth having?

const

Return a pointer to the data contained in this message.

Return the actual data pointer...

Note:

This is dangerous. Do we need to do this?

This function is dangerous, as it allows direct access. This should be changed.
