toString method

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

String toString() {
  StringBuffer ret = new StringBuffer("NewEdge(");

  ret.write("key:");
  if (this.key == null) {
    ret.write("null");
  } else {
    ret.write(this.key);
  }

  ret.write(", ");
  ret.write("props:");
  if (this.props == null) {
    ret.write("null");
  } else {
    ret.write(this.props);
  }

  ret.write(")");

  return ret.toString();
}
