C++ (Cpp) Set::capacity Examples

Example #1

void TestTools::set_capacity()
{
    Set<int> set;
    int n = set.capacity();
    QVERIFY(n == 0);

    for (int i = 0; i < 1000; ++i) {
        set.insert(i);
        QVERIFY(set.capacity() >= set.size());
    }
}

Example #2

void TestTools::set_reserve()
{
    Set<int> set;
    int n = set.capacity();
    QVERIFY(n == 0);

    set.reserve(1000);
    QVERIFY(set.capacity() >= 1000);

    for (int i = 0; i < 500; ++i)
        set.insert(i);

    QVERIFY(set.capacity() >= 1000);

    for (int j = 0; j < 500; ++j)
        set.remove(j);

    QVERIFY(set.capacity() >= 1000);

    set.clear();
    QVERIFY(set.capacity() == 0);
}
