com.aerospike.client.command.ExistsCommand

org.jboss.cache.commands.read.ExistsCommand

Checks whether a given node exists in current in-memory state of the cache. Does not acquire any locks in doing so (result may be dirty read). Does not attempt to load nodes from a cache loader (may return false if a node has been evicted).

Specifically used by the {@link org.jboss.cache.loader.ClusteredCacheLoader} toimplement {@link org.jboss.cache.loader.CacheLoader#exists(org.jboss.cache.Fqn)}

This is the equivalent of the old MethodCallDefinitions.existsMethod method call from 2.1.x.
