public Object
getContent(DataSource
The DataSource representing the data to be converted.
ds)

Implements jakarta.activation.DataContentHandler.getContent.

Return an object representing the data in its most preferred form.

public Object
getTransferData(ActivationDataFlavor
The ActivationDataFlavor representing the requested type.
df, DataSource
The DataSource representing the data to be converted.
ds)

Implements jakarta.activation.DataContentHandler.getTransferData.

Returns an object which represents the data to be transferred.

public ActivationDataFlavor[]
getTransferDataFlavors()

Implements jakarta.activation.DataContentHandler.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).

pack-priv static void
outputPreamble(multipart_signed.LineOutputStream lOut, MimeBodyPart part, String boundary)

internal preamble is generally included in signatures, while this is technically wrong, if we find internal preamble we include it by default.

private static String

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)

Implements jakarta.activation.DataContentHandler.writeTo.

Convert the object to a byte stream of the specified MIME type and write it to the output stream.

getContentback to summary
public Object getContent(DataSource ds) throws IOException

Implements jakarta.activation.DataContentHandler.getContent.

Doc from jakarta.activation.DataContentHandler.getContent.

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 getTransferDataFlavors method.

Parameters
ds:DataSource

The DataSource representing the data to be converted.

Returns:Object

The constructed Object.

Exceptions
IOException:
if the data can't be accessed
getTransferDataback to summary
public Object getTransferData(ActivationDataFlavor df, DataSource ds) throws IOException

Implements jakarta.activation.DataContentHandler.getTransferData.

Doc from jakarta.activation.DataContentHandler.getTransferData.

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.

Parameters
df:ActivationDataFlavor

The ActivationDataFlavor representing the requested type.

ds:DataSource

The DataSource representing the data to be converted.

Returns:Object

The constructed Object.

Exceptions
IOException:
  • if the handler doesn't support the requested flavor
  • if the data can't be accessed

public ActivationDataFlavor[] getTransferDataFlavors()

Implements jakarta.activation.DataContentHandler.getTransferDataFlavors.

Doc from jakarta.activation.DataContentHandler.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).

Returns:ActivationDataFlavor[]

The ActivationDataFlavors.

public void writeTo(Object obj, String _mimeType, OutputStream os) throws IOException

Implements jakarta.activation.DataContentHandler.writeTo.

Doc from jakarta.activation.DataContentHandler.writeTo.

Convert the object to a byte stream of the specified MIME type and write it to the output stream.

Parameters
obj:Object

The object to be converted.

_mimeType:String

The requested MIME type of the resulting byte stream.

os:OutputStream

The output stream into which to write the converted byte stream.

Exceptions
IOException:
errors writing to the stream
