All Implemented Interfaces:

Disposable

public class MimeMessageInputStreamSource

extends MimeMessageSource

implements Disposable

Takes an input stream and creates a repeatable input stream source for a MimeMessageWrapper. It does this by completely reading the input stream and saving that to a temporary file that should delete on exit, or when this object is GC'd.

Constructor Detail

MimeMessageInputStreamSource

public MimeMessageInputStreamSource(String key,
                                    InputStream in)
                             throws MessagingException

in - the stream containing the MimeMessage

Throws:

MessagingException - if an error occurs while trying to store the stream

Method Detail

getSourceId

public String getSourceId()

Returns the unique identifier of this input stream source

Specified by:

getSourceId in class MimeMessageSource

Returns:

the unique identifier for this MimeMessageInputStreamSource

getInputStream

public InputStream getInputStream()
                           throws IOException

Get an input stream to retrieve the data stored in the temporary file

Specified by:

getInputStream in class MimeMessageSource

Returns:

a BufferedInputStream containing the data

Throws:

IOException - if an error occurs while generating the InputStream

getMessageSize

public long getMessageSize()
                    throws IOException

Get the size of the temp file

Overrides:

getMessageSize in class MimeMessageSource

Returns:

the size of the temp file

Throws:

IOException - if an error is encoutered while computing the size of the message

dispose

public void dispose()

Specified by:

dispose in interface Disposable

See Also:

Finalizer that closes and deletes the temp file. Very bad.

We're leaving this in temporarily, while also establishing a more formal mechanism for cleanup through use of the dispose() method.
