    @class WebScriptObject

    @discussion WebScriptObjects are used to wrap script objects passed from

    script environments to Objective-C.  WebScriptObjects cannot be created

    directly.  In normal uses of WebKit, you gain access to the script

    environment using the "windowScriptObject" method on WebView.

    The following KVC methods are commonly used to access properties of the

    WebScriptObject:

    - (void)setValue:(id)value forKey:(NSString *)key

    - (id)valueForKey:(NSString *)key

    As it possible to remove attributes from web script objects the following

    additional method augments the basic KVC methods:

    - (void)removeWebScriptKey:(NSString *)name;

    Also the sparse array access allowed in web script objects doesn't map well to NSArray, so

    the following methods can be used to access index based properties:

    - (id)webScriptValueAtIndex:(unsigned int)index;

    - (void)setWebScriptValueAtIndex:(unsigned int)index value:(id)value;

    @interface WebScriptObject : NSObject
