Class InternalCacheSet<E>

java.lang.Object
org.infinispan.InternalCacheSet<E>
Type Parameters:
E - The element type
All Implemented Interfaces:
Iterable<E>, Collection<E>, Set<E>, CacheCollection<E>, CacheSet<E>, org.infinispan.commons.util.CloseableIteratorCollection<E>, org.infinispan.commons.util.CloseableIteratorSet<E>
public abstract class InternalCacheSet<E> extends Object implements CacheSet<E>
Base class for internal classes used in cache collections.

It extends CacheSet because that's what interceptors used return for KeySetCommand and EntrySetCommand, but because these classes are only used internally, we can avoid implementing most of the methods.

Subclasses only need to implement localPublisher(IntSet) and localPublisher(int), and a facade class like CacheBackedKeySet implements the rest of the CacheSet methods.

    • localPublisher

      public abstract org.reactivestreams.Publisher<E> localPublisher(int segment)
      Description copied from interface: CacheCollection
      Returns a publisher that will publish all elements that map to the given segment. Note this publisher may require going remotely to retrieve elements depending on the underlying configuration and flags applied to the original Cache used to create this CacheCollection.
      Specified by:
      localPublisher in interface CacheCollection<E>
      Parameters:
      segment - the segment that all published elements belong to
      Returns:
      Publisher that will publish the elements for the given segment

    • localPublisher

      public abstract org.reactivestreams.Publisher<E> localPublisher(org.infinispan.commons.util.IntSet segments)
      Description copied from interface: CacheCollection
      Returns a publisher that will publish all elements that map to the given segment. Note this publisher may require going remotely to retrieve elements depending on the underlying configuration and flags applied to the original Cache used to create this CacheCollection.
      Specified by:
      localPublisher in interface CacheCollection<E>
      Parameters:
      segments - the segments that all published elements belong to
      Returns:
      Publisher that will publish the elements for the given segments
