OOP berasal dari myobj.h:
struct shape_rectangle * rect ;
rect = malloc ( sizeof ( * rect ));
if (! rect ) return -1 ;
shape_rectangle_init ( rect );
shape_draw ( & rect -> shape );
shape_free ( & rect -> shape ); struct shape_ops ;
struct shape {
struct shape_ops * ops ;
struct color * _color ;
};
struct shape_ops {
void ( * _destructor )( struct shape * );
void ( * free )( struct shape * );
void ( * draw )( struct shape * );
struct shape_ops * __super ;
};
void shape_init ( struct shape * ); struct shape_rectangle * rect ;
shape_rectangle_init ( rect );
shape_draw ( & rect -> shape );
shape_free ( & rect -> shape ); struct shape_rectangle {
struct shape shape ;
};
void shape_rectangle_init ( struct shape_rectangle * ); struct shape_rectangle * rect ;
struct shape_circle * circle ;
shape_draw ( & rect -> shape );
shape_draw ( & circle -> shape ); // file: OOC.h
struct Class {
size_t size ;
void * ( * ctor ) ( void * self , va_list * app );
};
void * new ( const void * _class , ...) {
const struct Class * class = _class ; // assign the address of `struct String` class
void * p = calloc ( 1 , class -> size ); // allocate the sizeof(struct String);
assert ( p );
* ( const struct Class * * ) p = class ; // Force the conversion of p and set the argument `class` as the value of this pointer.
if ( class -> ctor ) {
va_list ap ;
va_start ( ap , _class );
p = class -> ctor ( p , & ap ); // Now what is `p` here, a `struct String` or `struct Class`.
// and if it is `struct Class` then how it convert to `struct String` in `String_ctor` function
// given below.
va_end ( ap );
}
return p ;
}
// file: mystring.h
#include "OOC.h"
struct String {
const void * class ; // must be first
char * text ;
};
static void * String_ctor ( void * _self , va_list * app ) {
struct String * self = _self ;
const char * text = va_arg ( * app , const char * );
self -> text = malloc ( strlen ( text ) + 1 );
assert ( self -> text );
strcpy ( self -> text , text );
return self ;
}
// Initialization
static const struct Class _String = {
