Package io.fabric8.kubernetes.client.informers.impl.cache

Class CacheImpl<T extends io.fabric8.kubernetes.api.model.HasMetadata>

  • Type Parameters:
    T - type for cache object
    All Implemented Interfaces:
    io.fabric8.kubernetes.client.informers.cache.Cache<T>, io.fabric8.kubernetes.client.informers.cache.Indexer<T>, io.fabric8.kubernetes.client.informers.cache.Store<T>
    public class CacheImpl<T extends io.fabric8.kubernetes.api.model.HasMetadata>
extends Object
implements io.fabric8.kubernetes.client.informers.cache.Cache<T>
    It basically saves and indexes all the entries.
    Index reads byIndex(String, String), indexKeys(String, String), index(String, HasMetadata) are not globally locked and thus may not be fully consistent with the current state
