Some coops stuff.
Miscellaneous coops extensions.
INSTANCE is a coops-instance.
SLOT is a symbol.
INITFORM is 'SLOT OBJECT.
The slot accessor recursion.[syntax] (slot@ INSTANCE SLOT ...) => *
Returns the slot value of the N'th named slot from INSTANCE.[syntax] (slot@ INSTANCE SLOT ... [= OBJECT])
Sets the slot value of the N'th named slot of INSTANCE to OBJECT.
(use coops coops-extras) ; Needlessly complex for example (define-class <first> () (next)) (define-class <second> (<first>) ()) (define-class <third> (<second>) ()) (define 1st (make <first> 'next (make <second> 'next (make <third> 'next "the end")))) (slot@ 1st next next next) ;=> "the end" (slot@ 1st next next next = "still the end") (slot@ 1st next next next) ;=> "still the end"
(From '@' macro by Dan Muresan.)
make/copy[procedure] (make/copy INSTANCE [INITFORM ...]) => coops-instance
Returns a copy of the object INSTANCE except where an INITFORM overrides an existing SLOT value of the INSTANCE.
describe-object[procedure] (describe-object INSTANCE [OUT (current-output-port)])
Prints information about the INSTANCE to the output-port OUT.
describe-object is a generic-procedure specializing the first argument.
A more detailed print-object for use in a REPL.
Some TInyCLOS inspired property readers.
Provides predicates and read accessors for coops objects.
OBJECT is a Scheme object.
CLASS is a coops class.
GENERIC is a coops generic-procedure.
METHOD is a coops generic-procedure method. Do not apply any but the supplied API to instances of this type!
instance-of?[procedure] (instance-of? OBJECT CLASS) => boolean
Is OBJECT an instance of the CLASS>?
class?[procedure] (class? OBJECT) => boolean
Is OBJECT an instance of the <standard-class>?[procedure] (check-class LOC OBJ [ARGNAM]) => *
[procedure] (error-class LOC OBJ [ARGNAM])
instance?[procedure] (instance? OBJECT) => boolean
Is OBJECT not an instance of the <standard-class>?[procedure] (check-instance LOC OBJ [ARGNAM]) => *
[procedure] (error-instance LOC OBJ [ARGNAM])
primitive-instance?[procedure] (primitive-instance? OBJECT) => boolean
[procedure] (primitive? OBJECT) => boolean
Is OBJECT an instance of the <primitive-object> class?
generic?[procedure] (generic? OBJECT) => boolean
Synonym for generic-procedure?.[procedure] (check-generic LOC OBJ [ARGNAM]) => *
[procedure] (error-generic LOC OBJ [ARGNAM])
method?[procedure] (method? OBJECT) => boolean
Is OBJECT a method of a generic-procedure?[procedure] (check-method LOC OBJ [ARGNAM]) => *
[procedure] (error-method LOC OBJ [ARGNAM])
class-precedence-list[procedure] (class-precedence-list CLASS) => (list-of class)
[procedure] (class-cpl CLASS) => (list-of class)
[procedure] (class-supers CLASS) => (list-of class)
Returns the superclasses of CLASS.
class-slots[procedure] (class-slots CLASS) => (list-of symbol)
Returns the slot names of CLASS.
class-direct-supers[procedure] (class-direct-supers CLASS) => (list-of class)
Returns the uninherited superclasses of CLASS.
class-direct-slots[procedure] (class-direct-slots CLASS) => (list-of symbol)
Returns the uninherited slot names of CLASS.
generic-anonymous?[procedure] (generic-anonymous? GENERIC) => boolean
Is GENERIC an unnamed generic-procedure.
generic-name[procedure] (generic-name GENERIC) => (union #f symbol)
Returns the name of GENERIC. The name is #f for an anonymous generic procedure.
generic-specialized-arguments[procedure] (generic-specialized-arguments GENERIC) => (list-of symbol)
The arguments that GENERIC is specialized upon.
generic-primary-methods[procedure] (generic-primary-methods GENERIC) => (list-of method)
[procedure] (generic-methods GENERIC) => (list-of method)
Returns the list of primary: methods for GENERIC.
generic-before-methods[procedure] (generic-before-methods GENERIC) => (list-of method)
Returns the list ofbefore: methods for GENERIC.
generic-after-methods[procedure] (generic-after-methods GENERIC) => (list-of method)
Returns the list of after: methods for GENERIC.
generic-around-methods[procedure] (generic-around-methods GENERIC) => (list-of method)
Returns the list of around: methods for GENERIC.
method-specializers[procedure] (method-specializers METHOD) => (list-of class)
Returns the classes that specialize METHOD.
method-procedure[procedure] (method-procedure METHOD) => procedure
Returns the procedure for METHOD.
(use coops coops-introspection) (define (print-methods generic) (for-each (lambda (m) (print (generic-name generic) " specialized by " (method-specializers m) " as " (method-procedure m))) (generic-methods generic)) )
- The introspection API is not for use in production code.
While useful it relies on knowledge of the internals of the coops implementation and Chicken. It is very brittle, especially the generics portion.
Suggested only for use during REPL development with coops.
