Constructor Detail

BoundaryDelimitedStream

protected BoundaryDelimitedStream(BoundaryDelimitedStream prev,
                                  int readbufsz)

Constructor to create the next stream from the previous one.

Parameters:

prev -

readbufsz -

Method Detail

newStreamNo

protected static int newStreamNo()

Method newStreamNo

Returns:

getNextStream

public BoundaryDelimitedStream getNextStream()

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.

getNextStream

protected BoundaryDelimitedStream getNextStream(int readbufsz)

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.

read
