构造器详细资料

MimePartDataSource

public MimePartDataSource(MimePart part)

Constructor, that constructs a DataSource from a MimePart.

参数:

part - the MimePart

方法详细资料

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:

getInputStream 在接口中 DataSource

返回:

decoded input stream

抛出:

IOException

另请参阅:

MimeMessage.getContentStream(), MimeBodyPart.getContentStream(), MimeUtility.decode(java.io.InputStream, java.lang.String)

getOutputStream

public OutputStream getOutputStream()
                             throws IOException

DataSource method to return an output stream.

This implementation throws the UnknownServiceException.

指定者:

getOutputStream 在接口中 DataSource

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:

getContentType 在接口中 DataSource

getName

public String getName()

DataSource method to return a name.

This implementation just returns an empty string.

指定者:

getName 在接口中 DataSource

getMessageContext

public MessageContext getMessageContext()

Return the MessageContext for the current part.

指定者:

getMessageContext 在接口中 MessageAware

返回:

the message context
