                                  int readbufsz)
                           throws java.io.IOException

Constructor to create the next stream from the previous one.

Parameters:

prev - the previous stream

readbufsz - how many bytes to make the read buffer

Throws:

java.io.IOException - if there was a problem reading data from prev

newStreamNo

protected static int newStreamNo()

Signal that a new stream has been created.

Returns:

getNextStream

public BoundaryDelimitedStream (src)  getNextStream()
                                      throws java.io.IOException

Gets the next stream. From the previous using the same buffer size to read.

Returns:

the boundary delmited stream, null if there are no more streams.

Throws:

java.io.IOException - if there was an error loading the data for the next stream

getNextStream

Gets the next stream. From the previous using new buffer reading size.

Parameters:

readbufsz -

Returns:

the boundary delmited stream, null if there are no more streams.

Throws:

java.io.IOException - if there was an error loading the data for the next stream
