Package org.infinispan.multimap.impl

Class EmbeddedMultimapCache<K,V>

java.lang.Object
org.infinispan.multimap.impl.EmbeddedMultimapCache<K,V>
All Implemented Interfaces:
org.infinispan.multimap.api.BasicMultimapCache<K,V>, MultimapCache<K,V>
public class EmbeddedMultimapCache<K,V> extends Object implements MultimapCache<K,V>
Embedded implementation of MultimapCache

Transactions

EmbeddedMultimapCache supports implicit transactions without blocking. The following methods block when they are called in a explicit transaction context. This limitation could be improved in the following versions if technically possible :
  • BasicMultimapCache.size()
  • BasicMultimapCache.containsEntry(Object, Object)
More about transactions in : the Infinispan Documentation.

Duplicates

MultimapCache can optionally support duplicate values on keys. {@link <pre> multimapCache.put("k", "v1").join(); multimapCache.put("k", "v2").join(); multimapCache.put("k", "v2").join(); multimapCache.put("k", "v2").join(); multimapCache.get("k").thenAccept(values -> System.out.println(values.size())); // prints the value 4. "k" -> ["v1", "v2", "v2", "v2"]
