removeTokenFromAllTokensEnumeration

removeTokenFrom is a function used in token management to remove a specific token from a token store, such as an in-memory cache, a database table, or a distributed cache. The function typically accepts a token identifier and a reference to the store or context in which the token is kept. The return value is commonly a boolean or status indicating whether a token was actually removed.

Behavior: If the token exists, it is deleted from the store and the function returns true. If the token does not exist, it may return false or succeed silently (idempotent). Some implementations may throw an error for invalid inputs or unauthorized calls. In asynchronous environments, the operation may emit events or complete a promise/future when the removal is committed.

Storage and performance: removeTokenFrom is agnostic to the underlying storage, which can include in-memory maps, relational databases, key-value stores, or distributed caches. Performance is typically O(1) for hash-based stores and O(log n) for balanced trees or dependent on database query costs. In distributed systems, token removal may require coordination or transactional guarantees to avoid races.

Security considerations: token revocation should be performed with proper authorization checks, audit logging, and, where applicable, coordination with token lifetimes, blacklists, or revocation lists. In stateless token schemes (for example, signed tokens like JWTs), removal affects access by maintaining a separate revocation mechanism rather than relying on the token's self-contained validity.
