示例1: main
int main(int argc, char *argv[]) {
if (argc < 2) {
cout << "usage: BloomFilterTest <bits>\n where bits is the bit count per variable" << endl;
return 1;
}
unsigned int bits = atoi(argv[1]), wrong = 0, counter = 0;
cout << "bits=" << bits << endl;
int limit = 1000000;
// take bits as parameter
BloomFilter BF (limit, (size_t) bits, (uint32_t) time(NULL));
// insert ints 0,...,1M
for (int j=0; j<limit;j++)
BF.insert(j);
// assert 0,...,1M
for (int j=0; j<limit;j++)
assert(BF.contains(j));
for (int j=limit; j < 2*limit ;j++) {
if (BF.contains(j))
wrong++;
counter++;
}
