Examples of ConsistentHashFactory

org.infinispan.client.hotrod.impl.consistenthash.ConsistentHashFactory
Factory for {@link org.infinispan.client.hotrod.impl.consistenthash.ConsistentHash} function. It will try to lookinto the configuration for consistent hash definitions as follows: consistent-hash.[version]=[fully qualified class implementing ConsistentHash] e.g. infinispan.client.hotrod.hash_function_impl.1=org.infinispan.client.hotrod.impl.consistenthash.ConsitentHashV1
If no CH function is defined for a certain version, then it will be defaulted to "org.infinispan.client.hotrod.impl.ConsistentHashV[version]". E.g. if the server indicates that in use CH is version 1, and it is not defined within the configuration, it will be defaulted to org.infinispan.client.hotrod.impl.ConsistentHashV1. @author Mircea.Markus@jboss.com @since 4.1
