isECI method

  1. @override
bool isECI(
  1. int index
)
override

Determines if a value is an ECI

@param index the index of the value

@return true if the value at position index is an ECI

@throws IndexOutOfBoundsException if the index argument is negative or not less than length

Implementation

@override
bool isECI(int index) {
  if (index < 0 || index >= length) {
    // IndexOutOfBoundsException
    throw IndexError.withLength(index, length);
  }
  return bytes[index] > 255 && bytes[index] <= 999;
}
