Constructor Detail

### BoundaryDelimitedStream

    protected BoundaryDelimitedStream(BoundaryDelimitedStream prev,

                               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:

    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.

  Parameters:
    `b` - is the array to read into.
    `off` - is the offset
    `len` -
  Returns:
    the number of bytes read. -1 if endof stream.
  Throws:
    `java.io.IOException`

### read

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

### read

    public int read()
             throws java.io.IOException

                                   int end)
                            throws java.io.IOException

  Read from the boundary delimited stream.

  Parameters:
    `searchbuf` - buffer to read from
    `start` - starting index
