        this(offset, _default_value);
}

construct the ByteField with its offset into its containing byte array and a default value of 0

Parameters:

offset - of the field within its byte array

Throws:

ArrayIndexOutOfBoundsException - if offset is negative

exception: ArrayIndexOutOfBoundsException - if offset is negative

 public ByteField(int offset,
    byte value) throws ArrayIndexOutOfBoundsException 
{
        if (offset <  0)
        {
            throw new ArrayIndexOutOfBoundsException(
                "offset cannot be negative");
        }
        _offset = offset;
        set(value);
}

construct the ByteField with its offset into its containing byte array and initialize its value

Parameters:

offset - of the field within its byte array

value - the initial value

Throws:

ArrayIndexOutOfBoundsException - if offset is negative

exception: ArrayIndexOutOfBoundsException - if offset is negative

 public ByteField(int offset,
    byte[] data) throws ArrayIndexOutOfBoundsException 
{
        this(offset);
        readFromBytes(data);
}

Construct the ByteField with its offset into its containing byte array and initialize its value from its byte array

Parameters:

offset - of the field within its byte array

data - the byte array to read the value from

Throws:

ArrayIndexOutOfBoundsException - if the offset is not within the range of 0..(data.length - 1)

exception: ArrayIndexOutOfBoundsException - if the offset is not within the range of 0..(data.length - 1)

 public ByteField(int offset,
    byte value,
    byte[] data) throws ArrayIndexOutOfBoundsException 
{
        this(offset, value);
        writeToBytes(data);
}

construct the ByteField with its offset into its containing byte array, initialize its value, and write its value to its byte array

Parameters:

offset - of the field within its byte array

value - the initial value

data - the byte array to write the value to

Throws:

ArrayIndexOutOfBoundsException - if the offset is not within the range of 0..(data.length - 1)

exception: ArrayIndexOutOfBoundsException - if the offset is not within the range of 0..(data.length - 1)

 public byte get() 
{
        return _value;
}

get the ByteField's current value

 public  void readFromBytes(byte[] data) throws ArrayIndexOutOfBoundsException 
{
        _value = data[ _offset ];
}

set the value from its offset into an array of bytes

 public  void readFromStream(InputStream stream) throws IOException, BufferUnderrunException 
{
        _value =
            (LittleEndian.readFromStream(stream,
                                         LittleEndianConsts.BYTE_SIZE))[ 0 ];
}

set the value from an InputStream

 public  void set(byte value) 
{
        _value = value;
}

set the ByteField's current value

 public  void set(byte value,
    byte[] data) throws ArrayIndexOutOfBoundsException 
{
        set(value);
        writeToBytes(data);
}

set the ByteField's current value and write it to a byte array

 public String toString() 
{
        return String.valueOf(_value);
}

return the value as a String

 public  void writeToBytes(byte[] data) throws ArrayIndexOutOfBoundsException 
{
        data[ _offset ] = _value;
}

write the value out to an array of bytes at the appropriate offset
