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.
| Modifier and Type | Method and Description |
|---|---|
| public Object | Returns: The constructed Object.The DataSource representing the data to be converted. ds)Return an object representing the data in its most preferred form. |
| public Object | Returns: The constructed Object.The ActivationDataFlavor representing the requested type. df, DataSource The DataSource representing the data to be converted. ds)Returns an object which represents the data to be transferred. |
| public ActivationDataFlavor[] | Returns: The ActivationDataFlavors.Returns an array of ActivationDataFlavor 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
The object to be converted. obj, String The requested MIME type of the resulting byte stream. mimeType, OutputStream The output stream into which to write the converted
byte stream. os)Convert the object to a byte stream of the specified MIME type and write it to the output stream. |
| getContent | back to summary |
|---|---|
| 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
ActivationDataFlavor returned by the

| getTransferData | back to summary |
|---|---|
| public Object getTransferData(ActivationDataFlavor df, DataSource ds) throws 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.
| |
| getTransferDataFlavors | back to summary |
|---|---|
| public ActivationDataFlavor[] getTransferDataFlavors() Returns an array of ActivationDataFlavor 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).
| |
| writeTo | back to summary |
|---|---|
| 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.
