Package org.infinispan.client.hotrod

Class RemoteCacheManager

  • All Implemented Interfaces:
    Closeable, AutoCloseable, org.infinispan.client.hotrod.jmx.RemoteCacheManagerMXBean, RemoteCacheContainer, BasicCacheContainer, Lifecycle
    public class RemoteCacheManager
extends Object
implements RemoteCacheContainer, Closeable, org.infinispan.client.hotrod.jmx.RemoteCacheManagerMXBean

    Factory for RemoteCaches.

    In order to be able to use a RemoteCache, the RemoteCacheManager must be started first: this instantiates connections to Hot Rod server(s). Starting the RemoteCacheManager can be done either at creation by passing start==true to the constructor or by using a constructor that does that for you; or after construction by calling start().

    NOTE: this is an "expensive" object, as it manages a set of persistent TCP connections to the Hot Rod servers. It is recommended to only have one instance of this per JVM, and to cache it between calls to the server (i.e. remoteCache operations)

    stop() needs to be called explicitly in order to release all the resources (e.g. threads, TCP connections).

                          boolean start)
        Create a new RemoteCacheManager using the supplied Configuration. The RemoteCacheManager will be started automatically only if the start parameter is true

      • RemoteCacheManager

        public RemoteCacheManager​(boolean start)

        Similar to RemoteCacheManager(Configuration, boolean), but it will try to lookup the config properties in the classpath, in a file named hotrod-client.properties. If no properties can be found in the classpath, defaults will be used, attempting to connect to 127.0.0.1:11222

        Refer to ConfigurationBuilder for a detailed list of available properties.

        Parameters:
        start - whether or not to start the RemoteCacheManager
        Throws:
        HotRodClientException - if such a file cannot be found in the classpath

      • getConfiguration

        public Configuration getConfiguration()
        Description copied from interface: RemoteCacheContainer
        Retrieves the configuration currently in use. The configuration object is immutable. If you wish to change configuration, you should use the following pattern: 
        
 ConfigurationBuilder builder = new ConfigurationBuilder();
 builder.read(remoteCacheManager.getConfiguration());
 // modify builder
 remoteCacheManager.stop();
 remoteCacheManager = new RemoteCacheManager(builder.build());
        Specified by:
        getConfiguration in interface RemoteCacheContainer
        Returns:
        The configuration of this RemoteCacheManager
        Since:
        5.3

      • getCacheNames

        public Set<String> getCacheNames()
        Description copied from interface: BasicCacheContainer
        This method returns a collection of all cache names.

        The configurations may have been defined via XML, in the programmatic configuration, or at runtime.

        Internal-only caches are not included.

        Specified by:
        getCacheNames in interface BasicCacheContainer
        Returns:
        an immutable set of cache names registered in this cache manager.

      • start

        public void start()
        Description copied from interface: Lifecycle
        Invoked on component start
        Specified by:
        start in interface Lifecycle

      • createChannelFactory

        public org.infinispan.client.hotrod.impl.transport.netty.ChannelFactory createChannelFactory()

      • isTransactional

        public boolean isTransactional​(String cacheName)
        Specified by:
        isTransactional in interface RemoteCacheContainer
        Returns:
        true if the cache with name cacheName can participate in transactions.

      • stop

        public void stop()
        Stop the remote cache manager, disconnecting all existing connections. As part of the disconnection, all registered client cache listeners will be removed since client no longer can receive callbacks.
