[x3d-public] C++ SAI: setters and addChildren return void

[John Carlson]

I had a look at:
https://github.com/Web3DConsortium/X3D/blob/master/ISO-IEC19777/ISO-IEC19777-4/ISO-IEC19777-4v3.3/ISO-IEC19777-4v3.3-IS/Part04/abstracts.html

I have some comments from a usability position.

For example, not returning “this” from setters, addChild and other adders
(I think only addChild does not exist), while good for debugging, requires
a lot more duplicated code, in the form of repeated use of variable names
in the code.  Please make me aware of examples if this is not required.

Here is an HAnim example:

https://github.com/coderextreme/X3DJSONLD/blob/master/src/main/cplusplus/net/coderextreme/data/JinLOA4.cpp

I don’t know if C++ contains the concept of Pascal’s “with” (creating a
context or namespace where repeated use of a variable name is not required)
and should would be documented in any C++ examples produced by the
Consortium (IMO).

Is there going to be an X3D XML to C++ stylesheet converter to give best
practices, or are we on our own?
