Method Detail

bitCount

protected int bitCount(int val,
                       int mark)

count the bits set in the integer up to a "terminator" mask.

Parameters:

val - int - count bits in integer

mark - int - terminator mask

intValue

protected int intValue(byte[] data,
                       int pos)

return the value of four successive bytes in an array as an integer value (big endian notation!)

Parameters:

data - byte[] - array of bytes to extract integer from

pos - int - offset into array with data.length >= pos + 4

Returns:

int - constructed value.

shortValue

protected short shortValue(byte[] data,
                           int pos)

return the value of twi successive bytes in an array as a short value (big endian notation!)

Parameters:

data - byte[] - array of bytes to extract integer from

pos - int - offset into array with data.length >= pos + 2

Returns:

short - constructed value.
