Class DatabaseImpl

java.lang.Object
  org.exist.xmldb.DatabaseImpl

public class DatabaseImpl

extends java.lang.Object

The XMLDB driver class for eXist. This driver manages two different internal implementations. The first communicates with a remote database using the XMLRPC protocol. The second has direct access to an embedded database instance running in the same virtual machine. The driver chooses an implementation depending on the XML:DB URI passed to getCollection(). When running in embedded mode, the driver can create a new database instance if none is available yet. It will do so if the property "create-database" is set to "true" or if there is a system property "exist.initdb" with value "true". You may optionally provide the location of an alternate configuration file through the "configuration" property. The driver is also able to address different database instances - which may have been installed at different places.

setDatabaseShutdownListener

public void setDatabaseShutdownListener(ShutdownListener listener)
                                 throws XMLDBException

Register a ShutdownListener for the current database instance. The ShutdownListener is called after the database has shut down. You have to register a listener before any calls to getCollection().

Parameters:

listener -
