• Status: RESOLVED FIXED

[Devin Rousso]

Leverage static `deserialize` functions, as well as `Multimap`s to hold the breakpoints.

I don't think this is our usual style.

    $ ack '^\s+\.[^.]' **/*.js -B 1 --ignore External

It is vastly more common to keep this on one line or to at least put the function name on the same line:

    return Array.from(this.breakpointsForSourceCode(sourceCode.sourceMap.originalSourceCode)).filter((breakpoint) => {
        return breakpoint.sourceCodeLocation.displaySourceCode === sourceCode;
    });

Some of the oldest ugliest code. Glad to see this cleaned up!

> Source/WebInspectorUI/UserInterface/Models/Breakpoint.js:41

After this I'd put:

    this._contentIdentifier = null;

It used to be `null` and would otherwise be `undefined` with this patch for special breakpoints.

We can make this an "Import / Export" section and put `deserialize` (or `fromJSON`) and `toJSON` next to each other to it is easy to compare them.

Now might be a good time to remove it!

Would be easier to avoid the lookup again by storing the new action in a local. Especially given someone could modify this_actions in the event handler.

Same here re: "Import / Export" or at least putting it by the toJSON.

Also, we don't use the "id" in deserialization, but we presumably do for the protocol? There should probably be a toProtocol() [protocol] instead of toJSON() [serialization].
