Example project (“p_ex1”)

#include <Event.h>

#include <PhHistogramFactory.hh>

#include <TH1.h>

#include <time.h>

#include <pmonitor.h>

PhHistogramFactory *hf;

int init_done = 0;

PhH1 *h; // the one histogram

int pinit()

{

if (init_done) return 1;

init_done = 1;

hf = PhHistogramFactory::instance();

if (hf)

{

h = hf->CreateH1F("H1", "Channel 0", 101,-49.5,49.5);

return 0;

}

else return -1;

}

int process_event (Event * e)

{

Packet *p = e->getPacket(1003);

if (p)

{

h->Fill (p->iValue(0));

delete p;

}

nsleep(100); // 100 milliseconds

return 0;

}

This is a pretty simple project -- we don’t have any additional user commands or anything non-standard.

We just fill the histograms and can work with them from the command prompt but not much else.

This is meant to work with the testEventiterator (packet 1003, etc)
