Subject: src/cpp-common/bt2/trace-ir.hpp: add nameSpace() methods where needed
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=6e082c859ae60cb521664a131aba012d5864219b;p=babeltrace.git

src/cpp-common/bt2/trace-ir.hpp: add nameSpace() methods where needed

The bt2::CommonEventClass::nameSpace() and
bt2::CommonStreamClass::nameSpace() methods make it possible to set and
get the namespace of event classes and stream classes (new feature
starting with MIP 1).
