operator bool() method from fcf::NTest::SharedPtrAny class

bool operator bool()

Available from version: 1.1.1

Provides a boolean representation of the pointer's validity.

The operator bool allows the fcf::NTest::SharedPtrAny instance to be used directly in boolean contexts, such as if statements or loops.

It returns true if the instance manages a valid object, and false if the instance is null (i.e., it does not point to any managed resource).

Result

bool

- Returns true if the pointer is non-null, false otherwise.

Example: Boolean Context Usage

Demonstrates how to use the fcf::NTest::SharedPtrAny object in conditional statements to check for nullity.

#define FCF_TEST_IMPLEMENTATION #include <fcfTest/test.hpp> #include <string> FCF_TEST_DECLARE("SharedPtrAny", "Demo", "BoolOperatorTest"){ struct Data { Data() {} }; // 1. Create a valid pointer fcf::NTest::SharedPtrAny validPtr = fcf::NTest::SharedPtrAny::make<Data>(); // 2. Create a null pointer fcf::NTest::SharedPtrAny nullPtr; // 3. Test valid pointer in an if-statement if (!validPtr) { FCF_TEST(false, "Valid pointer should evaluate to true"); } // 4. Test null pointer in an if-statement if (nullPtr) { FCF_TEST(false, "Null pointer should evaluate to false"); } // 5. Explicit boolean check FCF_TEST(static_cast<bool>(validPtr) == true, "Explicit cast should be true"); FCF_TEST(static_cast<bool>(nullPtr) == false, "Explicit cast should be false"); } 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; }
