Scala example source code file (

This example Scala source code file ( is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Scala source code examples by using tags.

All credit for the original source code belongs to; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

     * Populates <i>candidates</i> with a list of possible completions for the <i>buffer</i>.
     * The <i>candidates</i> list will not be sorted before being displayed to the user: thus, the

     * @param cursor        The current position of the cursor in the <i>buffer</i>
     * @param candidates    The {@link List} of candidates to populate
     * @return              The index of the <i>buffer</i> for which the completion will be relative
