operator-=() method from fcf::NTest::TimeDuration class

fcf::NTest::TimeDuration& operator-=(unsigned long long a_value)

fcf::NTest::TimeDuration& operator-=(const fcf::NTest::TimeDuration& a_rhs)

Class: fcf::NTest::TimeDuration

Package: fcfTest

File: test.hpp

Available from version: 1.2.5

Subtracts a duration or an arithmetic value from the current duration.

The operator-= method performs a subtraction assignment, reducing the current duration by the specified amount.

Arguments

unsigned long long a_value

- The amount to subtract.

Result

fcf::NTest::TimeDuration&

- Reference to the current object.

Example: Subtraction assignment

Demonstrating -= with both raw numeric types and TimeDuration objects.

#define FCF_TEST_IMPLEMENTATION #include <fcfTest/test.hpp> FCF_TEST_DEFINE("TimeDemo", "Basics", "SubAssignment") { fcf::NTest::TimeDuration d(1000ULL); // 1. Subtract raw numeric type d -= 400ULL; FCF_TEST(d.count() == 600ULL, d.count()); // 2. Subtract another TimeDuration fcf::NTest::TimeDuration d2(200ULL); d -= d2; FCF_TEST(d.count() == 400ULL, d.count()); } int main(int a_argc, char* a_argv[]) { bool error = false; fcf::NTest::cmdRun(a_argc, a_argv, fcf::NTest::CRM_RUN, &error); return error ? 1 : 0; }
