Examples of DataHandler

BaseClasses.DataHandler
com.denisk.appengine.nl.server.DataHandler
com.google.code.javax.activation.DataHandler
The DataHandler class provides a consistent interface to data available in many different sources and formats. It manages simple stream to string conversions and related operations using DataContentHandlers. It provides access to commands that can operate on the data. The commands are found using a CommandMap.
DataHandler and the Transferable Interface
DataHandler implements the Transferable interface so that data can be used in AWT data transfer operations, such as cut and paste and drag and drop. The implementation of the Transferable interface relies on the availability of an installed DataContentHandler object corresponding to the MIME type of the data represented in the specific instance of the DataHandler.
DataHandler and CommandMaps
The DataHandler keeps track of the current CommandMap that it uses to service requests for commands (getCommand, getAllCommands, getPreferredCommands). Each instance of a DataHandler may have a CommandMap associated with it using the setCommandMap method. If a CommandMap was not set, DataHandler calls the getDefaultCommandMap method in CommandMap and uses the value it returns. See CommandMap for more information.
DataHandler and URLs
The current DataHandler implementation creates a private instance of URLDataSource when it is constructed with a URL. @see javax.activation.CommandMap @see javax.activation.DataContentHandler @see javax.activation.DataSource @see javax.activation.URLDataSource
com.ning.compress.DataHandler
Interface used by {@link Uncompressor} implementations: receivesuncompressed data and processes it appropriately.
com.sun.messaging.jmq.jmsserver.data.handlers.DataHandler
Handler class which deals with normal (topic or queue) JMS messages
com.ziclix.python.sql.DataHandler
The DataHandler is responsible mapping the JDBC data type to a Jython object. Depending on the version of the JDBC implementation and the particulars of the driver, the type mapping can be significantly different. This interface can also be used to change the behaviour of the default mappings provided by the cursor. This might be useful in handling more complicated data types such as BLOBs, CLOBs and Arrays. @author brian zimmer @author last revised by $Author: bzimmer $ @version $Revision: 1.5 $
eu.planets_project.tb.api.data.util.DataHandler
This is the Testbed binary file-store wrapper. It takes copies of submitted resources and hold them, each with unique keys. The unique key must be used to retrieve the files. @author Andrew Lindley, ARC. Andrew Jackson, BL.

A data handler contains a number of callback methods. The most important implementing class is a database.
