// To generate genericslot.h from genericslot.h.pump, execute:
// /home/build/google3/third_party/gtest/scripts/pump.py genericslot.h.pump
// 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 */
// talk_base::GenericSlot1<int> slot(&foo, 0);
// foo.emit(5);
// EXPECT_TRUE(slot.callback_received());
// EXPECT_EQ(5, *(slot.arg1()));
