// Generic-slots are pure slots that can be hooked up to signals. They're
|
|
// mainly intended to be used in tests where we want to check if a signal
|
|
// was invoked and what arguments were passed. NOTE: They do not do any
|
|
// lifetime management of the arguments received via callbacks.
|
|
//
|
|
// Example:
|
|
// /* Some signal */
|
|
// sigslot::signal1<int> foo;
|
|
//
|
|
// /* We want to monitor foo in some test */
|
|
// rtc::GenericSlot1<int> slot(&foo, 0);
|
|
// foo.emit(5);
|
|
// EXPECT_TRUE(slot.callback_received());
|
|
// EXPECT_EQ(5, *(slot.arg1()));
|
