endofpriority

Endofpriority is a term occasionally used in computer science to denote the sentinel boundary beyond which priority levels are not explicitly defined. It serves as a marker in systems that organize tasks, events, or data items by priority, distinguishing items with a defined priority from those with no defined priority or from the end of the priority domain.

In data structures such as priority queues and in scheduling algorithms, endofpriority is typically implemented as a special sentinel value or constant (for example, None, infinity, or a named constant) that is used to terminate a sequence of priorities or to indicate that a given item has no explicit priority. It enables uniform iteration over priorities and helps detect exhaustion of the priority space.

The term is not standardized and may be defined differently across implementations and literature. Some models treat endofpriority as a top element outside the finite set of priorities; others use it as a lower-bound indicator meaning “no further priority levels.” In practice, designers choose a representation that integrates with their ordering, data types, and dispatch rules.

Since endofpriority is a coined or domain-specific term, it is mainly encountered in technical notes, code comments, or discussions about multi-level policies and priority-based processing. Related concepts include priority queue, sentinel value, and boundary of an ordered set.
