/**
|
|
* Construct a Target for a given URL object having various query parameters:
|
|
*
|
|
* host:
|
|
* {String} The hostname or IP address to connect to.
|
|
* port:
|
|
* {Number} The TCP port to connect to, to use with `host` argument.
|
|
* ws:
|
|
* {Boolean} If true, connect via websocket instread of regular TCP connection.
|
|
*
|
|
* type: tab, process, window
|
|
* {String} The type of target to connect to.
|
|
*
|
|
* If type == "tab":
|
|
* id:
|
|
* {Number} the tab outerWindowID
|
|
* chrome: Optional
|
|
* {Boolean} Force the creation of a chrome target. Gives more privileges to
|
|
* the tab actor. Allows chrome execution in the webconsole and see chrome
|
|
* files in the debugger. (handy when contributing to firefox)
|
|
*
|
|
* If type == "process":
|
|
* id:
|
|
* {Number} the process id to debug. Default to 0, which is the parent
|
|
* process.
|
|
*
|
|
* If type == "window":
|
|
* id:
|
|
* {Number} the window outerWindowID
|
|
*
|
|
* @param {URL} url
|
|
* The url to fetch query params from.
|
|
*
|
|
* @return A target object
