Implementation Note:

std::clog << msg
23
This expression is required for forms like NS_LOG_LOGIC (... << std::endl ...)
24
25
26
ns3::ParameterLogger (std::clog) << msg
27
This expression is required for NS_LOG_FUNCTION (... << vector ...)

IMO ParameterLogger should work for both cases, but it fails
30
with the error:
31
32
note: in expansion of macro NS_LOG_LOGIC (std::endl...
33
error: no match for operator<< (operand types are ns3::ParameterLogger
34
and <unresolved overloaded function type>)
35
36
note: candidate: template<class T> ns3::ParameterLogger&
37
ns3::ParameterLogger::operator<<(T)
38
note: template argument deduction/substitution failed
39
note: couldn't deduce template parameter T
40
41
Note that std::endl is templated manipulator function, which needs the
42
target stream to resolve it's own template parameters. The compiler
43
should deduce this from the ParameterLogger::operator<< <T> ()
44
implementation, but evidently fails to do so.
