// Autocompleter.Base handles all the autocompletion functionality
// that's independent of the data source for autocompletion. This
// includes drawing the autocompletion menu, observing keyboard
// and mouse events, and similar.
//
// Specific autocompleters need to provide, at the very least,
// a getUpdatedChoices function that will be invoked every time
// the text inside the monitored textbox changes. This method
// should get the text for which to provide autocompletion by
// invoking this.getToken(), NOT by directly accessing
// this.element.value. This is to allow incremental tokenized
// autocompletion. Specific auto-completion logic (AJAX, etc)
// belongs in getUpdatedChoices.
//
// Tokenized incremental autocompletion is enabled automatically
// when an autocompleter is instantiated with the 'tokens' option
// in the options parameter, e.g.:
// new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
// will incrementally autocomplete with a comma as the token.
// Additionally, ',' in the above example can be replaced with
// a token array, e.g. { tokens: [',', '\n'] } which
// enables autocompletion on multiple tokens. This is most
// useful when one of the tokens is \n (a newline), as it
// allows smart autocompletion after linebreaks.

// The local array autocompleter. Used when you'd prefer to
// inject an array of autocompletion options into the page, rather
// than sending out Ajax queries, which can be quite slow sometimes.
//
// The constructor takes four parameters. The first two are, as usual,
// the id of the monitored textbox, and id of the autocompletion menu.
// The third is the array you want to autocomplete from, and the fourth
// is the options block.
//
// Extra local autocompletion options:
// - choices - How many autocompletion choices to offer
//
// - partialSearch - If false, the autocompleter will match entered
//                    text only at the beginning of strings in the
//                    autocomplete array. Defaults to true, which will
//                    match text at the beginning of any *word* in the
//                    strings in the autocomplete array. If you want to
//                    search anywhere in the string, additionally set
//                    the option fullSearch to true (default: off).
//
// - fullSsearch - Search anywhere in autocomplete array strings.
//
// - partialChars - How many characters to enter before triggering
//                   a partial match (unlike minChars, which defines
//                   how many characters are required to do any match
//                   at all). Defaults to 2.
//
// - ignoreCase - Whether to ignore case when autocompleting.
//                 Defaults to true.
//
// It's possible to pass in a custom function as the 'selector'
// option, if you prefer to write your own autocompletion logic.
// In that case, the other options above will not apply unless
// you support them.

Namespace: UI

  Introduction:
    Prototype-UI is a library of user interface components based on the Prototype framework.
    Its aim is to easilly improve user experience in web applications.

    It also provides utilities to help developers.

  Guideline:
    - Prototype conventions are followed
    - Everything should be unobstrusive
    - All components are themable with CSS stylesheets, various themes are provided

  Warning:
    Prototype-UI is still under deep development, this release is targeted to developers only.
    All interfaces are subjects to changes, suggestions are welcome.

    DO NOT use it in production for now.

/*
Interface: UI.Options
  Mixin to handle *options* argument in initializer pattern.

  TODO: find a better example than Circle that use an imaginary Point function,
        this example should be used in tests too.

  It assumes class defines a property called *options*, containing
  default options values.

  Instances hold their own *options* property after a first call to <setOptions>.

  Example:
    > var Circle = Class.create(UI.Options, {
    >
    >   // default options
    >   options: {
    >     radius: 1,
    >     origin: Point(0, 0)
    >   },
    >
    >   // common usage is to call setOptions in initializer
    >   initialize: function(options) {
    >     this.setOptions(options);
    >   }
    > });
    >
    > var circle = new Circle({ origin: Point(1, 4) });
    >
    > circle.options
    > // => { radius: 1, origin: Point(1,4) }

  Accessors:
    There are builtin methods to automatically write options accessors. All those
    methods can take either an array of option names nor option names as arguments.
    Notice that those methods won't override an accessor method if already present.

     * <optionsGetter> creates getters
     * <optionsSetter> creates setters
     * <optionsAccessor> creates both getters and setters

    Common usage is to invoke them on a class to create accessors for all instances
    of this class.
    Invoking those methods on a class has the same effect as invoking them on the class prototype.
    See <classMethod> for more details.

    Example:
    > // Creates getter and setter for the "radius" options of circles
    > Circle.optionsAccessor('radius');
    >
    > circle.setRadius(4);
    > // 4
    >
    > circle.getRadius();
    > // => 4 (circle.options.radius)

  Inheritance support:
    Subclasses can refine default *options* values, after a first instance call on setOptions,
    *options* attribute will hold all default options values coming from the inheritance hierarchy.

    Group: Events
      List of events fired by a carousel

      Notice: Carousel custom events are automatically namespaced in "carousel:" (see Prototype custom events).

      Examples:
        This example will observe all carousels

        >   alert("Carousel with id " + event.memo.carousel.id + " has just been scrolled");

        > });

      Property: previousButton:enabled
        Fired when the previous button has just been enabled

      Property: previousButton:disabled
        Fired when the previous button has just been disabled

      Property: nextButton:enabled
        Fired when the next button has just been enabled

      Property: nextButton:disabled
        Fired when the next button has just been disabled

      Property: scroll:started
        Fired when a scroll has just started

      Property: scroll:ended
        Fired when a scroll has been done,
        memo.shift = number of elements scrolled, it's a float

      Property: sizeUpdated
        Fired when the carousel size has just been updated.
        Tips: memo.carousel.currentSize() = the new carousel size
