Framework Traits: Transients trait

Caches callback results in per-site WordPress transients.

Capabilities and extension points

Gets a cached value or computes it when the transient is absent.

If the transient already exists, it will be returned. Else, it will be generated from the callback result. A stored false is indistinguishable from a cache miss and therefore causes regeneration.

• param string $transient Transient name.
• param int $expiration Lifetime in seconds; zero requests no expiration.
• param callable $callable Callback producing the value to cache.
• param array $args Optional callback arguments. Default empty array.
• return mixed Transient value.

Computes a fresh value and replaces the transient.

• param string $transient Transient name.
