Method Detail

getUnsigned

public static IJIUnsigned getUnsigned(java.lang.Number value,
                                      int flag)

Returns an implementation for each of the unsigned type. Only 3 types are supported at present Byte, Short, Integer.

Since Java has no support for unsigned types, use a Short for a Byte, Integer for a Short and Long for an Integer. This is to accomodate the entire spectrum for the unsigned type and prevent the rollover problem.

Parameters:

value - Short, Integer, Long only

flag - JIFlags unsigned flags

Returns:

Throws:

java.lang.IllegalArgumentException - if the value is not an instance of the supported types or an incorrect flag has been provided.
