MemoryKachePersistence class final

An in-process, SDK-only persistence backend for typed cache entries.

Values are retained by reference and are not serialized or copied. This makes the backend suitable for process-local persistence, deterministic tests, and environments where callers intentionally own object mutation. Entries do not survive process termination.

Each stored key records the binding fingerprint and reified type used by its latest write. Reads require an exact match. A write under a new fingerprint authoritatively replaces the prior value; reusing one fingerprint for a different reified type remains an error. close is idempotent, releases all retained values, and causes every later operation other than close to fail.
