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([String prefix = '']) {
var buffer = StringBuffer();
buffer.writeln('${prefix}Policy: $policyIdentifier');
buffer.writeln(
policyQualifiers.map((q) => q.toString('${prefix}\t')).join('\n'));
return buffer.toString();
}
