Hi,
I have construct of the form
value=message.getProperties()["property"];
The expected property type is uint32. The value type has up until now
been "unsigned int", so (obviously) the call has worked just fine. But
then I changed it to a double (because I want to use it as a
floating-point later), and it will no longer work - get and "
InvalidConversion" exception with the message "Cannot convert from
uint32 to double (qpid/types/Variant.cpp:488)". This rather surprised
me; I can easily work around this, but why isn't an integer variant
convertible to a floating-point value?
Also, when doing some more tests, I realised that I also get an
exception when the property is missing. This was also not quite what I
expected, either - based on experience with "variant" types in other
libraries, I assumed that an "empty" variant would be convertible to
most types - giving a 0 or default-constructed value. Comments?
QPid version is 0.22.
