                              Object... args)

Check the specified boolean argument. Throws an IllegalStateException with the specified message if b is false.

Parameters:

b - Argument to check

message - Message for exception. May be null.

args - Arguments to place in message

checkNotNull

public static void checkNotNull(Object o)

Check the specified boolean argument. Throws an NullPointerException if o is false

Parameters:
