Examples of ObjectRegistry

chrriis.common.ObjectRegistry
A convenient class to register objects to an ID. @author Christopher Deckers
org.apache.bsf.util.ObjectRegistry
The ObjectRegistry is used to do name-to-object reference lookups. If an ObjectRegistry is passed as a constructor argument, then this ObjectRegistry will be a cascading registry: when a lookup is invoked, it will first look in its own table for a name, and if it's not there, it will cascade to the parent ObjectRegistry. All registration is always local. [??] @author Sanjiva Weerawarana @author Matthew J. Duftler
org.apache.tez.runtime.api.ObjectRegistry
A simple shared object registry to cache objects in the memory of the container running the task. This registry can be used to avoid re-creating objects like common hash-tables, dictionaries etc. and provide performance improvements. The cached objects have different life-cycles. If a task adds an object to the cache with Vertex life-cycle then that object is in the cache while the Vertex (to which the task belongs) is running. DAG life-cycle is while the DAG (to which that task belongs) is running. Session life-cycle is while the session (to which that task belongs) is running.
This interface is not supposed to be implemented by users.
org.apache.tez.runtime.common.objectregistry.ObjectRegistry
Preliminary version of a simple shared object cache to re-use objects across multiple tasks within the same container/JVM.
org.apache.woden.internal.util.ObjectRegistry
This class copied from WSDL4J. The ObjectRegistry is used to do name-to-object reference lookups. If an ObjectRegistry is passed as a constructor argument, then this ObjectRegistry will be a cascading registry: when a lookup is invoked, it will first look in its own table for a name, and if it's not there, it will cascade to the parent ObjectRegistry.
