contains method

bool contains(int line, int col)

checks if the given cell (line / col) is contained in this hit

Implementation

bool contains(int line, int col) {
  if (line < startLineIndex || line > endLineIndex) {
    return false;
  }
  if (line == startLineIndex && startLineIndex == endLineIndex) {
    return col >= startIndex && col < endIndex;
  }
  if (line == startLineIndex) {
    return col >= startIndex;
  }
  if (line == endLineIndex) {
    return col < endIndex;
  }
  // here we are sure that the given point is inside a full line match
  return true;
}
