Nice work - I think this will make using structured data significantly easier. /trunk/qpid/cpp/include/qpid/messaging/Message.h <https://reviews.apache.org/r/13328/#comment48917> To be consistent with the other constructors there should be one that takes a Variant now. /trunk/qpid/cpp/include/qpid/messaging/Message.h <https://reviews.apache.org/r/13328/#comment48915> I wonder if the API convention here is misused. The API is pretty consistent in using get...() for accessors and set...() for setters. plain content() is an accessor but doesn't match the convention. Perhaps to it should be getVariant() or maybe asVariant(). /trunk/qpid/cpp/src/qpid/types/encodings.h <https://reviews.apache.org/r/13328/#comment48923> I'm not sure a namespace is best here, maybe a struct with statics would be better here - in C++11 you can initialise static strings in class definition scopes, however here you will need a .cpp file. - Andrew Stitcher On Aug. 7, 2013, 7:17 p.m., Gordon Sim wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
