Class EntryMergePolicyFactoryRegistry


  • public class EntryMergePolicyFactoryRegistry
    extends Object
    A registry for EntryMergePolicyFactory implementations, which allows EntryMergePolicy implementations to be eagerly/lazily loaded across multiple contexts. The order in which EntryMergePolicyFactory implementations are added to the registry determines their priority, with createInstance(PartitionHandlingConfiguration) returning as soon as the first non-null implementation is encountered. In embedded mode we only expect a single factory implementation to be present as custom policy implementations are provided during runtime by the user or loaded via the Parser's ConfigurationBuilder's classloader. However, in server mode it's possible for users to deploy their custom policies to the server or use one of the default policies, therefore it's necessary for both the embedded factory and a server factory to be utilised.
