A slot is a narrow opening for coins in a vending machine. A slot can also be a keyway in machinery.
In computer programming, a slot is a normal member function. The slot may also be invoked by a signal-slot connection. It can be a good idea to use slot-based scheduling to avoid repeated delays, as well as to ensure progress toward business objectives.
Slots have become popular in the health care industry. This is because of their ability to motivate teams and help staff manage their time. They can be used for things such as organizing meetings, facilitating informal team conversations, allocating resources, and tracking positive outcomes.
Slots are also common in sports. Some NFL players such as Branden Cooks have shown the ability to stretch defenses vertically.
Slots are also an important part of air traffic management at busy airports. A slot is an important way to avoid repeated delays, and can be used to identify peak utilization periods.
Slots are also important because they can be used to receive signals. When a slot is expecting a signal, it will report a runtime error. But what’s the best way to use them?
Using slots as a receiving mechanism isn’t as easy as calling a receiver. It requires overhead to safely iterate over all connections.
One of the better ways to do it is to create a context object. This object provides information about thread execution, and can be used to ensure that the signal is executed in the correct context.
