toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  StringBuffer sb = StringBuffer();
  sb.write("====== WhereDataList ======\n");
  if (_whereStructList.length > 0) {
    _whereStructList.forEach((ws) {
      sb.write(ws);
    });
  } else {
    sb.write("(No where data)\n");
  }
  return sb.toString();
}
