javax.activation
public interface: DataContentHandler [javadoc |
source]
All Known Implementing Classes:
ObjectDataContentHandler, DataSourceDataContentHandler
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.
| Method from javax.activation.DataContentHandler Detail: |
|---|
 public Object getContent(DataSource ds) throws IOException
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. |
public Object getTransferData(DataFlavor df,
DataSource ds) throws UnsupportedFlavorException, IOException Returns an object which represents the data to be transferred.
The class of the object returned is defined by the representation class
of the flavor. |
public DataFlavor[] getTransferDataFlavors() 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). |
public void writeTo(Object obj,
String mimeType,
OutputStream os) throws IOException Convert the object to a byte stream of the specified MIME type
and write it to the output stream. |
