      • contains

        public boolean contains​(int segment,
                                Object key)
        Description copied from interface: SegmentedAdvancedLoadWriteStore
        Returns true if the storage contains an entry associated with the given key in the given segment

        The provided segment may be used for performance purposes, however it it is acceptable to ignore this argument.

        This method may be invoked invoked irrespective if the store is StoreConfiguration.segmented().

        Specified by:
        contains in interface SegmentedAdvancedLoadWriteStore<K,​V>
        Parameters:
        segment - the segment that the key maps to
        key - the key to see if exists
        Returns:
        true if the key is present in this loader with a given segment

        public io.reactivex.rxjava3.core.Flowable<K> publishKeys​(Predicate<? super K> filter)
        Description copied from interface: AdvancedCacheLoader
        Publishes all the keys from this store. The given publisher can be used by as many Subscribers as desired. Keys are not retrieved until a given Subscriber requests them from the Subscription.

        Specified by:
        publishKeys in interface AdvancedCacheLoader<K,​V>
        Parameters:
        filter - a filter - null is treated as allowing all entries
        Returns:
        a publisher that will provide the keys from the store

        entryPublisher in interface AdvancedCacheLoader<K,​V>
        Parameters:
        filter - a filter - null is treated as allowing all entries
        fetchValue - whether or not to fetch the value from the persistent store. E.g. if the iteration is intended only over the key set, no point fetching the values from the persistent store as well
        fetchMetadata - whether or not to fetch the metadata from the persistent store. E.g. if the iteration is intended only ove the key set, then no point fetching the metadata from the persistent store as well

        Description copied from interface: AdvancedCacheWriter
        Using the thread in the pool, removed all the expired data from the persistence storage. For each removed entry, the supplied listener is invoked.

        When this method returns all entries will be purged and no tasks will be running due to this loader in the provided executor. If however an exception is thrown there could be tasks still pending or running in the executor.
