Here's an example of setting up a list with integer objects, and
getting an average and counts from the Averager interface.

#import <simtools.h>
#import <analysis.h>
#import <defobj/Create.h>
#import <collections.h>

@interface Integer: CreateDrop
{
  int val;
}
+ create: aZone setIntValue: (int)val;
- (int)getIntValue;
@end

@implementation Integer
+ create: aZone setIntValue: (int)_val
{
  Integer *obj = [super create: aZone];
  
  obj->val = _val;
  return obj;
}

- (int)getIntValue
{
  return val;
}
@end

int
main (int argc, const char **argv)
{
  id <List> l;
  id <Averager> averager;
  unsigned i;

  initSwarmBatch (argc, argv);
  
  l = [List create: globalZone];

  for (i = 0; i < 10; i++)
    [l addLast: [Integer create: globalZone setIntValue: i]];

  averager = [Averager createBegin: globalZone];
  [averager setProbedClass: [Integer class]];
  [averager setProbedSelector: M(getIntValue)];
  [averager setCollection: l];
  averager = [averager createEnd];


  [averager update];

  printf ("item count: %u average: %f\n",
          [averager getCount],
          [averager getAverage]);

}
