toString method
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() {
if (serverMessage != null) return serverMessage.toString();
final buf = new StringBuffer(message);
if (exception != null) buf..write(' (')..write(exception)..write(')');
if (connectionName != null) buf..write(' #')..write(connectionName);
return buf.toString();
}
