@implementation NSApplication (ScriptingPlugin)

/* kvc methods for the 'Mattresses' AppleScript element.  Here we implement the methods

 necessary for maintaining the list of Mattresses inside of the application container.

 Note the names. In our scripting definition file we specified that the application container

 class contains an element of type 'Mattress', like so:

 <element type="Mattress"/>

 Cocoa will use the plural form of the class name when naming the property used by

 AppleScript to access the list of Mattresses, and we should use the property name

 when naming our methods.  So, using the property name, we name our methods as follows:

 - (NSArray *)mattresses;

 - (void)insertInMattresses:(id)mattress;

 - (void)insertInMattresses:(id)mattress atIndex:(unsigned)index;

 - (void)removeFromMattressesAtIndex:(unsigned)index;

 as such, we don't have any instance variables for storing our application

 class' data.  So, we use globals for that storage.  */
