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() {
StringBuffer buffer = StringBuffer();
buffer.write(source.fullName);
buffer.write("(");
buffer.write(offset);
buffer.write("..");
buffer.write(offset + length - 1);
buffer.write("): ");
//buffer.write("(" + lineNumber + ":" + columnNumber + "): ");
buffer.write(message);
return buffer.toString();
}
