    19  * A source container implementation that wraps V8 virtual project. Currently virtual project

    20  * has a flat file structure, so the container is accordingly one-level.

    21  * <p>

    22  * Unlike other implementation of {@link ISourceContainer} this class initially gets instantiated

    23  * with no data. In this state it serves as an empty container because actual VM scripts are

    24  * not available yet. Launch configuration UI will use it in this state more as a symbolic

    25  * place-holder in sources tab. Later when VM is connected, method

    26  * {@link #init(ISourceLookupDirector)} will be called and the actual content will be set.
