getByte

public int getByte(int streampos)

Inspect the middle of the byte stream accumulated so far

Parameters:

streampos - is the index of the byte to inspect

Returns:

a byte value from the stream

insertByte

public void insertByte(int streampos,
 int val)

Overwrite bytes that have already been written into the stream

Parameters:

streampos - is the index of the byte to overwrite

val - is the value to overwrite with

write

public void write(int val)

Dump a single byte to the packed byte stream

Specified by:

write in class OutputStream

Parameters:

val - is the byte to be written

write

public void write(byte[] byteArray,
 int off,
 int len)

Dump an array of bytes to the packed byte stream

Overrides:

write in class OutputStream

Parameters:

byteArray - is the byte array

find

             throws IOException

Write the accumulated packed byte stream onto the output stream

Parameters:

s - is the output stream receiving the bytes

Throws:

IOException - for stream errors
