Class LocalEnvironment

java.lang.Object
  org.modeshape.jcr.LocalEnvironment

All Implemented Interfaces:

Environment

public class LocalEnvironment
extends Object
implements Environment

An Environment that can be used within a local (non-clustered) process.

To use a custom Environment instance, simply create a RepositoryConfiguration as usual but then call the RepositoryConfiguration.with(Environment) with the Environment instance and then use the resulting RepositoryConfiguration instance.

When a ModeShape repository configuration defines cache containers with configuration files on the file system or the classpath, then a LocalEnvironment instance can be used as-is with no other configuration or setup.

If applications wish to programmatically configure the Infinispan caches or cache containers, then those configurations can be registered with a LocalEnvironment instance. Specifically, the addCacheContainer(String, CacheContainer) and addCacheContainerIfAbsent(String, CacheContainer) methods register a programmatically created instance of a CacheContainer. Alternatively, the defineCache(String, String, Configuration) method can be used to register a named cache with a programmatically created Infinispan cache configuration.

Description copied from interface: Environment

Get the cache container with the given name. Note that the name might be a logical name or it might refer to the location of an Infinispan configuration; the exact semantics is dependent upon the implementation.

Specified by:

getCacheContainer in interface Environment

Parameters:

name - the name of the cache container; may be null

Returns:

the cache container; never null

Parameters:

name - the name of the channel; may not be null

Returns:

the channel, or null if there is no such channel and the environment does not support clustering

Shutdown this environment, allowing it to reclaim any resources.

This method does nothing if the environment has been marked as shared.

Specified by:

doShutdown

protected void doShutdown()

isShared()

isShared
