IOException

unwrite

public void unwrite()
             throws IOException

remove one byte from the written outputstream

Throws:

IOException - if there is no more buffer to unwrite from

write

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

Overrides:

write in class OutputStream

Throws:

IOException

size

public long size()

get the number or bytes written to the OutputStream

Returns:

the size

toString

public String toString()

Overrides:

toString in class Object

toHex

public String toHex()

convert the current buffer for text... can be used for testing.

Returns:

the hex representation of the bytes in UTF-8

Parameters:

outputStream -

Throws:

IOException

mark

public void mark()
          throws IOException

Marks the current position in this input stream.

Throws:

IOException - if the length of OutputStream cannot be retrieved

reset

public void reset()
           throws IOException
