            throws ArrayIndexOutOfBoundsException

set the value from its offset into an array of bytes

Parameters:

data - the byte array from which the value is to be read

LittleEndian.BufferUnderrunException - if there is not enough data available from the InputStream

IOException - if an IOException is thrown from reading the InputStream

writeToBytes

void writeToBytes(byte[] data)
           throws ArrayIndexOutOfBoundsException

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

Parameters:

data - the array of bytes to which the value is to be written

Throws:

ArrayIndexOutOfBoundsException - if the offset is out of the array's valid index range
