i cannot seem to get my root files arranged the way i would like them to
be. i have written a macro, which just writes some generic objects to a
file, and places them in certain directories.
TFile *f = new TFile("dir.root", "RECREATE", "cdf root io file");
f->cd();
char *dirname[] = {"event1","event2","event3","event4","event5",
"event6","event7","event8","event9","event10"};
for (int i = 1; i <= 10; i++)
{
cevent2 *ch1 = new cevent2;
ch1->met = i*100;
f->mkdir(dirname[i-1]);
f->cd(dirname[i-1]);
ch1->Write("event");
f->cd("/");
}
this works out fine. there is one "cevent2" object inside each directory.
however, if i try this outside the root enviroment, i get a vastly
different (and boggling result): no objects are written, but the
directories exist, and now the "event1" directory has one subdirectory:
"event2"; "event2" has one subdirectory "event3"; etc. the only thing i
have changed is now it is in a main function of a c++ program. is there
some manipulative functions i am not using right, or is there a better way
to move around in file in non-interactive mode??
#include <windows.h>
#include "TFile.h"
#include "cevent2_cint.h"
int WINAPI WinMain(HANDLE hInstance, HANDLE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
extern void InitGui();
VoidFuncPtr_t initfuncs[] = { InitGui, 0 };
TROOT fileio("fileio","Test of cdf i/o" ,initfuncs);
TFile *f = new TFile("dir.root", "RECREATE", "cdf root io file");
f->cd();
char *dirname[] = {"event1","event2","event3","event4","event5",
"event6","event7","event8","event9","event10"};
for (int i = 1; i <= 10; i++)
{
cevent2 *ch1 = new cevent2;
ch1->met = (float)i*100;
f->mkdir(dirname[i-1]);
f->cd(dirname[i-1]);
ch1->Write("event");
f->cd("/");
}
return 1;
}
i would *really* like to be able to write files that look like:
(top) |
|-event1 |
|-(assorted objects associated w/ event1)
|
|-event2 |
|-(assorted objects associated w/ event2)
|
:
:
|-eventn |
|-(assorted objects associated w/ eventn)
any help is, as always, GREATLY appreciated. thanks!!
