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() {
final buffer = StringBuffer();
buffer.writeln('StompFrame {');
buffer.writeln(' command: $command');
buffer.writeln(' headers: {');
for (final entry in headers.entries) {
buffer.writeln(' ${entry.key}: ${entry.value}');
}
buffer.writeln(' }');
if (body != null) {
buffer.writeln(' body: ${body!.length} bytes');
} else {
buffer.writeln(' body: null');
}
buffer.write('}');
return buffer.toString();
}
