code: public static <T> T isTrueArgument(final String name, final T value, final boolean condition) {
          if (!condition) {
              throw new IllegalArgumentException("state should be: " + name);
          }
          return value;
      }
docs: Throw IllegalArgumentException if the condition if false, otherwise return the value.  This is useful when arguments must be checked
  within an expression, as when using {@code this} to call another constructor, which must be the first line of the calling
  constructor.
  
  @param <T>       the value type
  @param name      the name of the state that is being checked
  @param value     the value of the argument
  @param condition the condition about the parameter to check
  @return          the value
  @throws java.lang.IllegalArgumentException if the condition is false
