Member Function Documentation

+ (void) appendTo:		(Cons **)	pcons
item:		(id)	o

Appends item:o to *pcons or creates new cell if *pcons is null.

Parameters:

	pcons	pointer to the list
	o	object to append

- (void) append:

(id)

o

Appends o to end of list.

- (void) appendList:

(Cons *)

o

Appends argument list to end of self.

Self now owns all of the argument list.

- (void) nilCars

Sets all cars in list to nil.

Does not free cars.

- (id) stealCar

Returns CAR then nils it in cell.

We must assume ownership of return value, since the cell was the previous owner due to the fact that cells free all CAR's when they are free'd.

- (id) stealCdr

Returns CDR then nils it in cell.

We must assume ownership of return value, since the cell was the previous owner due to the fact that cells free all CAR's when they are free'd.
