Mapeia as chaves do Redis na memória local adotando Lazy Load.

Specified by:

init in interface CacheSource<Data extends Cacheable>

store

public void store(Data data)

Salva o dado simultaneamente na memória local e no Redis (em Base64).

Specified by:

store in interface CacheSource<Data extends Cacheable>

remove

public void remove(String cacheKey)

Remove o item da memória local e do Redis.

Specified by:

remove in interface CacheSource<Data extends Cacheable>

has

public boolean has(String cacheKey)

Verifica se a chave existe na memória local ou no Redis.

Specified by:

has in interface CacheSource<Data extends Cacheable>

values
