bind ... "class" "selector" -- ... objects ``bind''
execute the method for selector in class.
<bind> class selector-xt -- xt objects ``<bind>''
xt is the method for the selector selector-xt in
class.
bind' "class" "selector" -- xt objects ``bind'''
xt is the method for selector in class.
[bind] compile-time: "class" "selector" -- ; run-time: ... object -- ... objects ``[bind]''
compile the method for selector in class.
class parent-class -- align offset objects ``class''
start a new class definition as a child of
parent-class. align offset are for use by
field etc.
class->map class -- map objects ``class->map''
map is the pointer to class's method map; it
points to the place in the map to which the selector offsets
refer (i.e., where object-maps point to).
class-inst-size class -- addr objects ``class-inst-size''
used as class-inst-size 2 ( class -- align size ),
gives the size specification for an instance (i.e. an object)
of class.
class-override! xt sel-xt class-map -- objects ``class-override!''
xt is the new method for the selector sel-xt in
class-map.
construct ... object -- objects ``construct''
initializes the data fields of object. The method for the
class object just does nothing ( object -- ).
current' "selector" -- xt objects ``current'''
xt is the method for selector in the current class.
[current] compile-time: "selector" -- ; run-time: ... object -- ... objects ``[current]''
compile the method for selector in the current class.
current-interface -- addr objects ``current-interface''
this variable contains the class or interface currently being defined.
dict-new ... class -- object objects ``dict-new''
allot and initialize an object of class class in
the dictionary.
drop-order class -- objects ``drop-order''
drops class's wordlists from the search order. No
checking is made whether class's wordlists are actually
on the search order.
end-class align offset "name" -- objects ``end-class''
name execution: -- class
ends a class definition. The resulting class is class.
end-class-noname align offset -- class objects ``end-class-noname''
ends a class definition. The resulting class is class.
end-interface "name" -- objects ``end-interface''
name execution: -- interface
ends an interface definition. The resulting interface is
interface.
end-interface-noname -- interface objects ``end-interface-noname''
ends an interface definition. The resulting interface is
interface.
exitm -- objects ``exitm''
exit from a method; restore old this.
heap-new ... class -- object objects ``heap-new''
allocate and initialize an object of class class.
implementation interface -- objects ``implementation''
the current class implements interface. I.e., you can
use all selectors of the interface in the current class and its
descendents.
init-object ... class object -- objects ``init-object''
initializes a chunk of memory (object) to an object of
class class; then performs construct.
inst-value align1 offset1 "name" -- align2 offset2 objects ``inst-value''
name execution: -- w
w is the value of the field name in this
object.
inst-var align1 offset1 align size "name" -- align2 offset2 objects ``inst-var''
name execution: -- addr
addr is the address of the field name in
this object.
interface -- objects ``interface''
starts an interface definition.
;m colon-sys --; run-time: -- objects ``;m''
end a method definition; restore old this.
m: -- xt colon-sys; run-time: object -- objects ``m:''
start a method definition; object becomes new this.
method xt "name" -- objects ``method''
name execution: ... object -- ...
creates selector name and makes xt its method in
the current class.
object -- class objects ``object''
the ancestor of all classes.
overrides xt "selector" -- objects ``overrides''
replace default method for selector in the current class
with xt. overrides must not be used during an
interface definition.
[parent] compile-time: "selector" -- ; run-time: ... object -- ... objects ``[parent]''
compile the method for selector in the parent of the
current class.
print object -- objects ``print''
prints the object. The method for the class object prints
the address of the object and the address of its class.
protected -- objects ``protected''
set the compilation wordlist to the current class's wordlist
public -- objects ``public''
restore the compilation wordlist that was in effect before the
last protected that actually changed the compilation
wordlist.
push-order class -- objects ``push-order''
add class's wordlists to the search-order (in front)
selector "name" -- objects ``selector''
name execution: ... object -- ...
creates selector name for the current class and its
descendents; you can set a method for the selector in the
current class with overrides.
this -- object objects ``this''
the receiving object of the current method (aka active object).
<to-inst> w xt -- objects ``<to-inst>''
store w into the field xt in this object.
[to-inst] compile-time: "name" -- ; run-time: w -- objects ``[to-inst]''
store w into field name in this object.
to-this object -- objects ``to-this''
sets this (used internally, but useful when debugging).
xt-new ... class xt -- object objects ``xt-new''
makes a new object, using xt ( align size -- addr ) to
get memory.
