Class
LimitedCollection
Collection with optional FIFO eviction when a new key is inserted at capacity. Construction is Map-safe: options are never passed to `super()`, so subclasses can call `super({ maxSize, onEvict })` without Map treating the options object as an iterable.

Properties
bounded
: boolean (readonly)Whether this collection enforces a finite capacity.
maxSize
: number (readonly)onEvict
: ((key: , value: ) => void) | null (readonly)Methods
clone
(): LimitedCollection<, >Clone into a new LimitedCollection with the same limits (no `onEvict` callback).
set
(key: , value: ): thisInsert or update an entry. When at capacity and `key` is new, the oldest entry is removed (FIFO by Map insertion order) and `onEvict` is invoked if set.
| Param | Type | Description |
|---|---|---|
| key | K | |
| value | V |
sweep
(filter?: (value: , key: ) => boolean): numberRemove entries matching `filter` (or all if omitted). Returns count removed. Does not invoke `onEvict` — callers that need cascade teardown should handle it.
