DUMP for Maps [FEATURE REQUEST] [message #27231]

Hi Mirek,

Could you please add a macro that would dump ArrayMap/VectorMap including the keys? I really miss it when debugging some of my programs. If I am not mistaken, the closest thing we have now is "DUMPC(map.GetKeys());DUMPC(map);", which is far from easy to use.

Something like this in Core/diag.h would be totally sufficient:

#define DUMPM(c) UPP::LockLog(), UPP::DumpMap(VppLog() << #c << ':' << UPP::EOL, (c)), UPP::UnlockLog()

template <class T>
void DumpMap(Stream& s, const T& t) {
	s << LOG_BEGIN;
	for(int i = 0; i < t.GetCount(); i++)
		s << '[' << i << "] = ("<< t.GetKey(i) << ") " << t[i] << EOL;
	s << LOG_END;
}

Best regards,
Honza

Good idea. It is there...

why not have a

String ToString() const;

function for them as well? making possible

LOG(containerInstance) ;

this kind of idea i posted into 'code style', really liked it in C# beeing able to inspect no matter which class instance in debugger..

Well, I have a little problem with creating a single String here, as the result can get pretty big. Perhaps it is non-issue, but...

for those classes predestinated to produce large Strings, one could limit output to say 1000 chars or so..inside the ToString()..

i found this thing to be quite usefull when debugging over LOG
