Convert file located in OSGi Bundle to IFile

Image
By User



I have an installed bundle (org.osgi.framework.Bundle) in my running eclipse. There is a file in this bundle. I have the path to the file and i can represent this file by an URL (java.net.URL) by using URL url = bundle.getEntry("/folder/file") .





Is there a way to get a handle of this file of type IFile (org.eclipse.core.resources.IFile)?





I need a reference of the file located in the installed osgi bundle of type IFile. But I don't want to copy the file temporary on my local disk (like workspace).





Thanks in advance!

    It's difficult. An IFile represents an actual file rather than an entry in an archive. You would need to build an Eclipse FileSystem (EFS) representation for the archive, but that's likely to be a lot of work.

    What are you trying to achieve? There's probably something you can do that is much simpler.

    If you have an eclipse plugin / editor or something like this try:

    //get the workspace
    IWorkspace workspace= ResourcesPlugin.getWorkspace();

    //create the path to the file
    IPath location= new Path(yourURL.getPath());

    //try to get the IFile (returns null if it could not be found in the workspace)
    IFile file= workspace.getRoot().getFileForLocation(location);

    if (file == null) {
    //not found in the workspace, get the IFileStore (external files)
    IFileStore fileStore = EFS.getLocalFileSystem().getStore(location);
    return fileStore;
    } else {
    // file found, return it
    return file;
    }


    Helpfull could be also:

    url = FileLocator.toFileURL(yourURL);


    and/or

    URL resolvedUrl = FileLocator.resolve(url);


    After this you can create the input for your editor (I think you want to use it there?)

    Object file = myGetFile();
    IEditorInput input;
    if (file instanceof IFile) {
    input = new FileEditorInput((IFile)file);
    else {
    if (file instanceof IFileStore) {
    input = new FileStoreEditorInput((IFileStore)file);
    } else {
    throw new MyException("file is null, not found");
    }
    }


    I hope this will help you.

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
