Class BatcherFactory

java.lang.Object
  com.netflix.logging.messaging.BatcherFactory

public class BatcherFactory
extends java.lang.Object

A simple singleton factory class that finds the batchers by name. Batchers are also created by the factory if needed. The users of the batcher have to simply override the MessageProcessor to specify what to do with the batched messages. It is the user's responsibility to make sure the name is unique (ie) a FQCN would be ideal for a name. The user should also remove the batcher from the cache during shutdown or when they do not need it. The methods are not synchronized for performance reasons and there is very little downside of not synchronizing it as the last put wins and the already existing objects are garbage collected.
