构造方法详细信息

MimePartDataSource

public MimePartDataSource(MimePart part)

Constructor, that constructs a DataSource from a MimePart.

方法详细信息

getInputStream

public InputStream getInputStream()
                           throws IOException

Returns an input stream from this MimePart.

This method applies the appropriate transfer-decoding, based on the Content-Transfer-Encoding attribute of this MimePart. Thus the returned input stream is a decoded stream of bytes.

This implementation obtains the raw content from the Part using the getContentStream() method and decodes it using the MimeUtility.decode() method.

指定者：

接口 DataSource 中的 getInputStream

返回：

decoded input stream

抛出：

IOException

getOutputStream

public OutputStream getOutputStream()
                             throws IOException

DataSource method to return an output stream.

This implementation throws the UnknownServiceException.

指定者：

接口 DataSource 中的 getOutputStream

抛出：

IOException

getContentType

public String getContentType()

Returns the content-type of this DataSource.

This implementation just invokes the getContentType method on the MimePart.

指定者：

接口 DataSource 中的 getContentType

getName

public String getName()

DataSource method to return a name.

This implementation just returns an empty string.

指定者：

接口 DataSource 中的 getName

getMessageContext

public MessageContext getMessageContext()

Return the MessageContext for the current part.

指定者：

接口 MessageAware 中的 getMessageContext
