What Is a Slot?
A slot is a place in the composition hierarchy where a group can be stored. Each group may have one or more slots and its slots are managed by the SlotTable, an internal data structure that tracks groups, keys, remembered values, and other information. The SlotTable is built and updated at runtime, matching the composition hierarchy and application state.
Slot is an internal data structure used by the Compose compiler to manage groups, key-value pairs, and other memory-managed values. It is also a component that can be extended and manipulated by a user through the Compose API. The Slot Table is a table of standard slots, which are either computed with data entered in a table or selected by the user. Each slot has a slot name and dimension. The slot names are mapped to the SlotTable attributes of the Compose instance, and the dimension attribute values indicate which of the available dimensions will be used for the resulting value.
While some slots are designed for specific purposes, the most common use of slot is to secure parts that cannot be held by the machine’s grips, such as the base of a test fixture or specimen holders in an automated testing system. This is accomplished using a commercially available T-slot table, which features inverted T-shaped grooves along the sides of the table, into which bolts, studs, or threaded rods are attached. The parts are then secured in the slot table with a clamp or other attachment device.
Payouts on slot machines can be a little confusing to players, especially for those who have just started playing. A slot’s pay table is an essential tool that outlines winning combinations and payouts, showing players which symbols to look for to get the most money from a spin. In addition, a pay table can help players understand how different bonus games and scatters work as well as how wild symbols can make a winning combination.
While a slot’s pay table may take the form of an actual table with columns and rows, it is often more recognizable as an on-screen display in video or online slot games. This type of pay table, such as that found in the Zeus II game mentioned above, may read more like a menu or scroll-down feature and offer a lot more information than just the different ways a winning spin pays out.
