Two objects that compare equal must also have the same hash value, but the reverse is not necessarily true. 返回对象的哈希值(如果它有的话)。哈希值是整数。它们在集合或字典查找元素时用来快速比较集合的元素或字典的键。相同大小的数字有相同的哈希值。
mylist.sort(compare_nocase); // comparison, not case sensitive. bool compare_nocase (const std::string& first, const std::string& second){ unsigned int i=0; while ( (i<first.length()) && (i<second.length()) ) { if (tolower(first[i])<tolower(second[i])) return true; ...
The fact that None is a singleton allows you to compare for None using the is keyword, like you did when creating decorators with optional arguments: Python if _func is None: return decorator_name else: return decorator_name(_func) Using is returns True only for objects that are the ...
QCOMPARE(model->data(index(0, 2)), 5); } include MyModelTest.moc 在上面的示例中,我们创建了三个测试用例,testRowCount()、testColumnCount()和testData()。这些测试用例分别测试模型的行数、列数和数据。每个测试用例都使用QTest::newTestCase()函数创建,并使用QTest::addColumn()函数添加输入参数...
