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
String toString() {
var base = "";
if (op.isNotEmpty) {
base += op + " ";
}
base += "join ${ident(table.toString())}";
if (ons.isNotEmpty) {
base += " on " + ons.map((e) => e.toString()).toList().join("");
}
return base;
}
