Class Overlay

  • public class Overlay
extends java.lang.Object

    This class was built using the Chrome Remote Dev-Tools A.P.I., which is specified by two JSON-RPC Files. These files were obtained from the Chrome Dev Tools Protocol Git Hub Page, which has a "Tip of Tree" (the latest) API-Specification Page Here: JSON-RPC Protocol Specification.

    These files were converted into this Java-Browser (CDP) Library. The intention is to have them function in a similar fasion to the Node.js Tool known as 'Puppeteer', Microsoft's 'Playwright' and of course the Main-Stay 'Selenium.' The Java-HTML JAR Library merely implements the Java Types & Commands defined by Google's DevTools Protocol.

    🧠 View the Google CDP API:

    This domain provides various functionality related to drawing atop the inspected page.

    The top-level description and explanation for this class (this comment, at the top this Java-Doc Page) is repeated, verbatim, across all of the domain classes which comprise Google's CDP API.

    This class is intended to be used with a Browser Instance

    These methods have been tested, to some degree, using Google Chrome. In order to use this class you must start a web-browser instance and make a connection to the browser using a Remote Debugging Port. Google-Corporation is the developer of this API, but any browser which accepts a Remote Debug Port Connection over Web-Sockets.

    Google-Chrome was used during the development process of the classes in this particular package. Lately, it has been asserted Microsoft has switched to using the Chrome Browser-Engine for its Microsoft Edge Internal Code-Base. Therefore, there may some functionality available when running the methods in this class with Microsoft-Edge.

    Check whether the your Web-Browser will allow itself to be driven by the Web-Socket RDP-Port 9223. See the examples available in package Torello.Browser to undertand how to build a PageConn and BrowserConn Web-Socket Connection, and how to build a WebSocketSender instance in order to execute the methods in this class.

    Web-Socket & JSON API:   
    Every one of the methods that reside in this class are designed to do nothing more than:

    1. Accept Parameters from the User, and "Marshall Them" into a Valid JSON-Request
    2. Transmit the Marshalled Request-JSON to a Headless Web-Browser over a Web-Socket Connection
    3. Receive BOTH that Command-Results AND any Browser Event-Firings from the Web-Socket
    4. Parse JSON Method-Results and Browser-Event Firings, and Subsequently Convert them to Standard Java-Types
    5. Report these Method-Results and Browser-Events to the User via a User-Registered, Event-Listener (Events) or a Promise Object (Command Responses / Results)

    Unlike the bulk of the Java HTML JAR Library, there is very little native Java-Code, and very little testing that may be done on any of the classes & methods in this package. The code inside these classes does nothing more than marshall-and-unmarshall Java-Types into Json-Requests (and vice-versa). The Java-Script & Browser modules inside of a Google-Chrome instance are, theoretically, handling these requests, and returning their results (or events) over the Web-Socket Connection.

    It has been asserted (by Google Chrome Developers) that some of these methods are only "partially working" or "experimental".


    Asking Chat-GPT for Help:   
    The LLM otherwise known as "Chat-GPT" does, indeed, have an expert level of knowledge about the "Remote DevTools Protocol". The API that the Chrome DevTools Protocl (CDP) exports is extremely well understood by the LLM, and generally I have found that Chat-GPT understands (by 2 or 3 orders of magnitude) better what my Auto-Generated JSON-Wrappers can do in controlling a Web-Browser than I could ever possibly hope to understand.

    Though not available today, there will soon be an automatically downloadable Token-Stream (AI Embeddings) BUTTON available on my Java-Doc Pages that should hopefully make it extremely easy to post my code-base, RAG Style, to Chat-GPT and other LLM's when 'interogating' them. Presently, because my "Get Token Stream Button" does not exist yet on any of my pages, what you can do is copy-and-paste any Method-Signature from any one of these pages and then ask Chat-GPT to explain what that Browser or Java-Script Function is actually doing. It is very likely to give you some pretty neat answers.

    I have found that every single one of the Domains, Types & Events which are offered by the CDP Protocol (though not documented very well by Google), are perfectly understood by the A.I. LLM - literally to the point where it does know (much better than I ever could) what my own code base actually does!

    Try it out, it's a lot of fun. Note that this package and these classes were originally developed solely to be able to execute the Java-Script that a browser executes when visiting a Web-Site. Complete HTML-Page Content can be scraped (using the HTML Data-Scraping Tools in Java-HTML) off of Web-Sites that have dynamic / Java-Script Generated Content.


    Conspicuous Boxed-Types Usage:
    You may notice that there are many methods that have parameters which accept, for instance, an Integer, instead of a primitive int. Just to remind the readiner, in Java Programs a Boxed Type is a standard Java-Primitive which has been converted into an Object-Reference. The use of Boxed-Types in this code base is an easy-and-fast-way to allow for the concept of "Optional Parameters" or "Optional Field Value."

    Whenever you see a method that accepts an Integer, the reason for this Parameter-Type choice is actually to allow a user to pass 'null' to it. This is a simple way to ELIDE passing any value at all to parameters which Google-Chrome would otherwise assert are "Optional." Whenever you pass 'null' to a Boxed-Types in this class, the Json-Processor will simply eliminate that Object-Property from the command altogether; and the browser will simply not receive any value for that parameter when that command is invoked.

    The Java Language Specification does not have an easy or well defined means of accepting optional method parameters; so Boxed-Types and 'null' are utilized here. Note that 'null' may be passed to any Command Method-Parameter that is listed as Optional on the Java-Doc Page description for that parameter.



    Stateless Class:
    This class neither contains any program-state, nor can it be instantiated. The @StaticFunctional Annotation may also be called 'The Spaghetti Report'. Static-Functional classes are, essentially, C-Styled Files, without any constructors or non-static member fields. It is a concept very similar to the Java-Bean's @Stateless Annotation.

        🡇  ⇈  ⮫ 🗕  🗗  🗖 
        public static final java.lang.String inspectModeCanceled
        Fired when user cancels the inspect mode.

        This is Marker-Event. Marker-Event's are events that do not possess any data or fields at all. When such events are fired by the browser, the Web-Socket sends nothing more than the name of the event in the packet. The Java-HTML CDP Implementation (this library) has not actually created a dedicated Java Event-Type for this Browser Event.

        This specific static field is actually just declared a String.
        inspectModeCanceled has not been 'reified' into an actual nested / inner class of its own, at all.
