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.
Return an object representing the data in its most preferred form.
Generally this will be the form described by the first DataFlavor
returned by the getTransferDataFlavors method.
param
ds The DataSource representing the data to be converted.
Returns an array of DataFlavor objects indicating the flavors the
data can be provided in. The array should be ordered according to
preference for providing the data (from most richly descriptive to
least descriptive).
