Method Signal():signal() Foundation
Posts a signal to wake up waiting threads.
:signal() --> selfThis method returns self.
The :signal() method posts the event semaphore, changing its state to signaled. This action releases threads that are currently waiting on this Signal object through the :wait() method.
When a signal is posted, at least one waiting thread will be released. If multiple threads are waiting, the operating system determines which thread(s) get released based on thread scheduling priorities.
The signal remains in the signaled state until a thread successfully waits on it with reset enabled (the default behavior), which then resets it back to non-signaled state. Multiple calls to :signal() while already in signaled state are allowed and harmless.
