                           throws 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:

IOException - if there was a problem reading data from prev

Method Detail

newStreamNo

protected static int newStreamNo()

Signal that a new stream has been created.

Returns:

---

getNextStream

public BoundaryDelimitedStream getNextStream()
                                      throws 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:

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

---

getNextStream

protected BoundaryDelimitedStream getNextStream(int readbufsz)
                                         throws IOException

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:

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

---

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Read from the boundary delimited stream.

Parameters:

b - is the array to read into.

off - is the offset

len -

Returns:

the number of bytes read. -1 if endof stream.

Throws:

IOException

---

read

public int read(byte[] b)
         throws IOException

Read from the boundary delimited stream.

Parameters:

b - is the array to read into. Read as much as possible into the size of this array.

read

public int read()
         throws IOException

Read from the boundary delimited stream.

Returns:

The byte read, or -1 if endof stream.

Throws:

IOException

close

public void close()
           throws IOException

Closes the stream.

Throws:

IOException
