The term slot is used to refer to the opening between two face-off circles on the offensive zone. These are the areas with the highest probability of scoring without deflection.
Slots are also used for receiving signals. Emitting a signal connected to a slot is about ten times slower than calling the receiver directly. However, this is worth the overhead.
Slots can be defined to be virtual or to be a physical connection. The latter requires marshalling parameters. A private slot can be invoked in an unrelated class. If a class that is not related to the slot emitted a signal, the receiver will be invoked in that class instead.
Slots are normally used in a member function. To connect a signal to a slot, use the QObject::connect() method. This method uses the SLOT and SIGNAL macros. When the compiler compiles the code, it will check compatibility and if the signal is valid.
Slots are often used in air traffic control. They ensure that repeated delays are avoided. At busy airports, slots are a common tool to manage air traffic.
Many companies rely on slot-based scheduling to help employees meet deadlines and schedule appointments. They can also be used to organize informal team meetings. Professionals like financial consultants may use the technology to plan objectives and communicate changes in the schedule.
Slot-based schedules can also be used to track positive outcomes and make improvements to the workflow. In addition, slot-based scheduling can improve communication between departments and staff, which increases engagement.
