Constructor Detail

BoundaryDelimitedStream

protected BoundaryDelimitedStream(BoundaryDelimitedStream prev,
                       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

Method Detail

newStreamNo

protected static int newStreamNo()

Signal that a new stream has been created.

Returns:

getNextStream

public BoundaryDelimitedStream 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

protected BoundaryDelimitedStream getNextStream(int readbufsz)
                                         throws java.io.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:

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

read

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

Read from the boundary delimited stream.

Overrides:

read in class java.io.FilterInputStream

Parameters:

b - is the array to read into.

off - is the offset

read

public int read(byte[] b)
         throws java.io.IOException

Read from the boundary delimited stream.

Overrides:

read in class java.io.FilterInputStream

Parameters:
