Module: ScopedCache

ScopedCache.invalidateWhen

Invalidates the entry associated with the specified key in the cache when the predicate returns true for the cached value.

When to use

Use to remove an already-cached scoped value only when the successful cached value satisfies a predicate.

Details

Returns true only when a successful cached value matches and is removed. It returns false for absent, expired, failed, or non-matching entries.

Gotchas

A matching invalidation closes the entry scope and releases its resources.

• invalidate for unconditional removal by key
