Fields

• line_buffer

   ByteLineBuffer line_buffer

• line_bytes

   ByteBuf line_bytes

• boundary

   ByteBuf boundary

• crlf

   ByteBuf crlf

• child_headers

   InternetHeaders child_headers

• state

   int state

• BOUNDARY_NONE

   protected static final int BOUNDARY_NONE

• BOUNDARY_TERMINATOR

   protected static final int BOUNDARY_TERMINATOR

• BOUNDARY_SEPARATOR

   protected static final int BOUNDARY_SEPARATOR

• MULTIPART_PREAMBLE

   protected static final int MULTIPART_PREAMBLE

• MULTIPART_HEADERS

   protected static final int MULTIPART_HEADERS

• MULTIPART_FIRST_LINE

   protected static final int MULTIPART_FIRST_LINE

• MULTIPART_LINE

   protected static final int MULTIPART_LINE

• MULTIPART_EPILOGUE

   protected static final int MULTIPART_EPILOGUE

Constructors

• MimeMultipart

   public MimeMultipart(String content_type, 
                        InternetHeaders headers)

Methods

• computeBoundary

   protected void computeBoundary()

• defaultSubpartType

   public String defaultSubpartType()

When a sub-part doesn't have a content-type specified, this method returns the default type. The default is "text/plain", but, for example, the "multipart/digest" handler overrides this to "message/rfc822". Note that this is a class method.

• pushBytes

   public void pushBytes(ByteBuf bytes)

Buffers the bytes into lines, and calls process_line() on each line.

Overrides:
pushBytes in class MimeObject

• pushEOF

   public void pushEOF()

Flushes the line buffer, and (maybe) calls process_line() one last time.

Overrides:
pushEOF in class MimeContainer

• process_line

   private void process_line(ByteBuf line)

Called for each line of the body of this multipart. Maintains a state machine and decides what the line means.

• checkBoundary

   protected int checkBoundary(ByteBuf line_buf)

• createMultipartChild

   protected void createMultipartChild()

• push_child_line

   private void push_child_line(ByteBuf line_buf, 
                                boolean first_line_p)
