    /* The Mattress class is a container for trinkets and treasures.

    Two points of interest in this class are the weight and value

    accessor methods that we use to implement the weight and value

    AppleScript properties.  These accessors implement read only

    properties and they return a calculated result reflecting the sum

    total of the weights of all of the trinkets and treasures

    contained in the Mattress.

    We take care of most of the 'infrastructure' type operations

    needed for scripting in the Element class (the superclass of the

    Trinket class), so all we have to worry about here is storage management

    and providing accessors for the properties.*/

@interface Mattress : Element {

    NSMutableArray *theTrinkets;

    NSMutableArray *theTreasures;

}

    /* storage management */

- (id)init;

- (void)dealloc;

    /* kvc method for the 'weight' AppleScript property.  Note that rather

    than simply returning a value, this method calculates its result by

    summing the weights of all of the trinkets and treasures contained

    in the Mattress.

    Also note, 'weight' is a declared as a read only property in our scripting

    definition file so we have not defined a 'setWeight:' method here.  */

- (NSNumber *)weight;

    /* kvc method for the 'value' AppleScript property.  Here also rather

    than simply returning a value, this method calculates its result by

    summing the values of all of the treasures contained in the Mattress.

    And, as with the 'weight' property, 'value' is a declared as a read

    only property in our scripting definition file so we have not

    defined a 'setValue:' method here. */

- (NSNumber *)value;

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

    necessary for maintaining the list of trinkets inside of a Mattress.  Note the names.

    In our scripting definition file we specified that the 'Mattress' class contains an

    element of type 'trinket', like so:

        <element type="trinket"/>

    Cocoa will use the plural form of the class name, 'trinkets',  when naming the

    property used by AppleScript to access the list of Mattresss, and we should use

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

    name our methods as follows:

        - (NSArray*) trinkets;

        -(void) insertInTrinkets:(id) trinket;

        -(void) insertInTrinkets:(id) trinket atIndex:(unsigned)index;

        -(void) removeFromTrinketsAtIndex:(unsigned)index;

    */

    /* return the entire list of trinkets */

- (NSArray*)trinkets;

    /* insert a trinket at the beginning of the list */

- (void)insertInTrinkets:(id)trinket;

    /* insert a trinket at some position in the list */

- (void)insertInTrinkets:(id)trinket atIndex:(unsigned)index;

    /* remove a trinket from the list */

- (void)removeFromTrinketsAtIndex:(unsigned)index;

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

    necessary for maintaining the list of trinkets inside of a Mattress.  Note the names.

    In our scripting definition file we specified that the 'Mattress' class contains an

    element of type 'treasure', like so:

        <element type="treasure"/>

    Cocoa will use the plural form of the class name, 'treasures',  when naming the

    property used by AppleScript to access the list of Mattresss, and we should use

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

    name our methods as follows:

        - (NSArray*) treasures;

        -(void) insertInTreasures:(id) treasure;

        -(void) insertInTreasures:(id) treasure atIndex:(unsigned)index;

        -(void) removeFromTreasuresAtIndex:(unsigned)index;

    */

    /* return the entire list of treasures */

- (NSArray *)treasures;

    /* insert a treasure at the beginning of the list */

- (void)insertInTreasures:(id)treasure;

    /* insert a treasure at some position in the list */

- (void)insertInTreasures:(id)treasure atIndex:(unsigned)index;

    /* remove a treasure from the list */

- (void)removeFromTreasuresAtIndex:(unsigned)index;

    /* methods used for randomizing the weights and values of

     elements contained inside of the mattress.  These methods are called

     by the -setRandomWeight: and -setRandomValue: methods, but they have been

     separated out so they can also be called by objects containing the

     mattress objects.*/

- (void)randomizeWeightBetweenMinimum:(NSNumber *)minimum andMaximum:(NSNumber *)maximum;

- (void)randomizeValueBetweenMinimum:(NSNumber *)minimum andMaximum:(NSNumber *)maximum;

    /* The following methods are called by Cocoa scripting in response

     to the randomize weight and randomize value AppleScript commands when
