-------------------------------------
Notes from chat:
kvdr: vector<int64_t> , vector<string> or other fixed type should encode as an
array by default. vector<proton::value> or vector<proton::scalar> will encode
as a list by default because the encoded type of value/scalar may not be
uniform.
gsapienz is now known as gsapienz_WLcall
kvdr: there are tricks to force the encoding however.
aconway, ok, thanks, let me look again at my code...

aconway, yes, you are right. I have a std::vector<proton::value>
kvdr: suppose I know that all the scalars in vector<scalar> v; are integers and
I want to force the whole thing to encode as an array of uin32_t:
Lei is now known as Lei_brb

value x; encoder(x) << encoder::array(v, PROTON::UINT)
kvdr: after that, x will contain the vector<scalar> encoded as AMQP array of
uint - or it will throw if any of the scalars can't be converted to uint.

> URL: https://issues.apache.org/jira/browse/PROTON-1795
> Project: Qpid Proton
> Issue Type: Bug
> Components: cpp-binding
> Affects Versions: proton-c-0.21.0
> Reporter: Alan Conway
> Assignee: Alan Conway
> Priority: Major
> Fix For: proton-c-0.22.0
>
>
> The complex type mapping section of the doc is brief and cryptic:
>
> [http://qpid.apache.org/releases/qpid-proton-0.21.0/proton/cpp/api/types_page.html]
>
> Needs review and improvement, including (but not limited to)
> * explain why we allow conversion of AMQP maps to/from sequences:
> order-preserving
> * clarify use of #include files to enable all or selected conversions.
> * include example code
