-----------------------------------
Summary: c++ provide access to message maps as proton::value
Key: PROTON-1288
URL: https://issues.apache.org/jira/browse/PROTON-1288
Project: Qpid Proton
Issue Type: Bug
Components: cpp-binding
Affects Versions: 0.14.0
Reporter: Alan Conway
Assignee: Alan Conway
Fix For: 0.15.0
We need to provide access to the message property maps as a proton::value.
Given
{code}
std::map<string, scalar> my_map;
proton::message m;
{code}
Here are some options:
1. Add new message accessor: proton::value& properties_value()
proton::get(m.properties_value(), my_map)
2. Add value() accessor to cached_map
proton::get(m.properties().value(), my_map)
3. Make cached_map : public proton::value()
proton::get(m.properties(), my_map)
3 is neatest, 1 provides a clearer separation between the case where you want a
convenient cached map vs. you want to decode to your own C++ map, work on it,
and possibly re-encode it later. I lean towards 3. but open to persuasion.
