--------------------------------------------
Hi Michael,
I have attached the files and need to mention the latest changes I made
recently. Since there is only one EventTarget (thus there are no Ancestor
EventTargets) in this case I ignored the "useCapture" in addActionListener()
and removeActionListener(). In dispatchEvent(Event evt) we have to get the
Event's type and check whether there are any EventListeners listening on the
particular Event. So I implemented a class called ListenerCount.java which is
similar to LCount.java(used in DocumentImpl) to keep track of the counts on the
EventListeners registered on the EventTarget.
I added initLoadEvent() and initProgressEvent() to LoadEventImpl.java and
ProgressEventImpl.java classes respectively. After instantiating objects from
these classes I call the initXXXEvent("XXX", false, false) passing "false"
values on canBubbleArg and cancelableArg parameters.
Can you review the dispatchEvent() and other changes I have done and tell
me how should I improve on them.
Thanks.
> [GSoC]: Asynchronous LSParser and parseWithContext
> --------------------------------------------------
>
> Key: XERCESJ-1429
> URL: https://issues.apache.org/jira/browse/XERCESJ-1429
> Project: Xerces2-J
> Issue Type: New Feature
> Components: DOM (Level 3 Load & Save)
> Affects Versions: 2.9.1
> Reporter: Michael Glavassevich
> Assignee: Thiwanka Somasiri
> Labels: gsoc2011
> Attachments: AsynchronousDOMParserImplPatch.txt,
> ListenerCountPatch.txt, LoadEventImplPatch.txt, ProgressEventImplPatch.txt
>
>
> The goal of this project is to complete the implementation of the DOM Level 3
> LSParser. Though Xerces has a functional LSParser, there are a couple parts
> of the spec which still need to be implemented. This includes an asynchronous
> [1] version which returns from the parse method immediately and builds the
> DOM tree on another thread as well as parseWithContext [2] which allows a
> document fragment to be parsed and attached to an existing DOM.
> Possible Mentors: Michael Glavassevich
