DataContentHandler JDK 1.6)

Description

public interface DataContentHandler

The DataContentHandler interface is implemented by objects that can be used to extend the capabilities of the DataHandler's implementation of the Transferable interface.

The DataContentHandler interface is implemented by objects that can be used to extend the capabilities of the DataHandler's implementation of the Transferable interface. Through DataContentHandlers the framework can be extended to convert streams in to objects, and to write objects to streams.

Applications don't generally call the methods in DataContentHandlers directly. Instead, an application calls the equivalent methods in DataHandler. The DataHandler will attempt to find an appropriate DataContentHandler that corresponds to its MIME type using the current DataContentHandlerFactory. The DataHandler then calls through to the methods in the DataContentHandler.
