Class LastByTableFactory

java.lang.Object

com.illumon.iris.db.tables.databases.LastByTableFactory

public class LastByTableFactory
extends Object

Creates a last by table based on our XML last by configuration file. The OnDiskQueryDatabase will create a LastByTableFactory, which loads the XML; and then call the getTable method to actually instantiate a table. The readXmlConfig is also used by the LastByIntradayLoggerFactory so that we can generate appropriate loggers for the last by tables, hooking into the DatabaseTools and IntradayLoggerFactory.
