Constructor Detail

BoundaryDelimitedStream

protected BoundaryDelimitedStream(BoundaryDelimitedStream prev,
                                  int readbufsz)
                           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.
Returns:
the number of bytes read. -1 if endof stream.
Throws:
IOException

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

mark

public void mark(int readlimit)
mark the stream. This is not supported.

Parameters:
readlimit -

reset

public void reset()
           throws IOException
reset the stream. This is not supported.

Throws:
IOException

markSupported

public boolean markSupported()
markSupported return false;

Returns:

available

public int available()
              throws IOException
Throws:
IOException

boundaryPosition

protected int boundaryPosition(byte[] searchbuf,
                               int start,
                               int end)
                        throws IOException
Read from the boundary delimited stream.

Parameters:
searchbuf - buffer to read from
start - starting index
end - ending index
Returns:
The position of the boundary. Detects the end of the source stream.
Throws:
IOException - if there was an error manipulating the underlying stream

finalClose

protected void finalClose()
                   throws IOException
Close the underlying stream and remove all references to it.

Throws:
IOException - if the stream could not be closed

printarry

public static void printarry(byte[] b,
                             int start,
                             int end)
Method printarry

Parameters:
