Method Detail

check

public static void check(int i,
                         String subject,
                         String error)
                  throws IllegalArgumentException

Checks the parameter range.

Parameters:

i - The integer to check to be in the range of an unsigned byte integer (8 bits).

subject - The subject of the exception message - may be null. This should not end with a punctuation character.

error - First sentence of the exception message - may be null. This should not end with a punctuation character.

Throws:

IllegalArgumentException - If i is less than MIN_VALUE or greater than MAX_VALUE.

check

public static void check(int i)
                  throws IllegalArgumentException

Checks the parameter range.

Parameters:

i - The integer to check to be in the range of an unsigned byte integer (8 bits).

Throws:

IllegalArgumentException - If i is less than MIN_VALUE or greater than MAX_VALUE.
