  org.eaglei.search.logging.AsynchronousLogger

Direct Known Subclasses:

AsynchronousLoggerCount, AsynchronousLoggerInstance, AsynchronousLoggerSearch

public abstract class AsynchronousLogger
extends java.lang.Object

Class providing asynchronous logging of events using a BlockingQueue. Specify a new or existing table in the constructor, along with the build ID and ontology ID. If you do not want one or the other of the IDs, set them to an empty string or to null. Extend this abstract class to create a new logger for a specified table. Implement the abstract methods with the details of the table and rows. See AsynchronousLogger for an example.
