Detailed Description

Slot class - a smart pointer to Data which provides for copy-on-write of the Data it manages

Additionally, Slot makes use of pointer alignment to encode additional forms into a pointer: encoded Integers (31 bit integer values) and one additional form which will be used for `immediate' values such as Promise and Future.

Note: can't make arrays of Slot - no default constructor

void init ()
[protected]

initialize Slot to NULL

Data * mkInteger ()
[protected const]

convert an encoded integer into an instance of Integer

inline bool isEncInt ()
[const]

predicate: is Slot an encoded Integer?

Slot (Data *d = NULL)

default constructor - construct NULL Slot

Slot (const Data *d)

construct from const Data*

Slot (int l)

Integer constructor - construct Slot from integer

Slot (Data &d)

reference constructor - construct Slot from Data

Slot (const char *str)

construct Slot from a string

Parameters:
strstring to assign to this

Slot (const Slot& f)

copy constructor - dups reference

Parameters:
fconst Slot& to which to assign this

Slot (Slot &s)

copy constructor - dups reference

Parameters:
sSlot& to which to assign this

Slot& operator= (const Slot& f)

assignment operator. Initializes Slot

Parameters:
fSlot& to which to assign this

Slot& operator= (Data *d)

assignment operator. Initializes Slot

Parameters:
dData* to which to assign this

Slot& operator= (int i)

assignment operator. Initializes Slot

Parameters:
iinteger to which to assign this
