Macro Definition Documentation

◆ Z_NAMED_CLASS

#define Z_NAMED_CLASS char *name;

an inheritance of named class.

Z_NAMED_CLASS macro works as a keyword to inherit a named class, namely, a class which can be identified by a string.

The inheritance can have a string to represent its name, which is referred by zName(). Use zNameSet() to set the name. Use zNameFree() to free the name string.

When searching an instance with a name name from an array of the class, call zNameFind( array, n, name, ptr ); where array is the pointer to array, n is the size of the array, name is a string to be referred, and ptr is a pointer to the element found. If it fails to find a corresponding element, the null pointer set for ptr.

◆ ZNONAME

#define ZNONAME "noname"

the default name for no-name.

◆ zNamePtr

#define zNamePtr ( c ) (c)->name

◆ zNameSetPtr

#define zNameSetPtr	(	c,
		p
	)	( (c)->name = (p) )

◆ zName

#define zName ( c ) ( (c) && zNamePtr(c) ? zNamePtr(c) : ZNONAME )

◆ zNameSet

#define zNameSet	(	c,
		n
	)	zNameSetPtr( c, zStrClone(n) )

◆ zNameFree

#define zNameFree ( c ) zFree( zNamePtr(c) )

◆ zNameFind

#define zNameFind	(	array,
		n,
		name,
		ptr
	)

Value:

do{\
  int __z_name_find_id;\
  (ptr) = NULL;\
  if( (name) != NULL && strcmp( (name), ZNONAME ) && (array) != NULL )\
    for( __z_name_find_id=0; __z_name_find_id<(n); __z_name_find_id++ )\
      if( zNamePtr( &(array)[__z_name_find_id] ) &&\
          !strcmp( (name), zName( (&(array)[__z_name_find_id]) ) ) ){\
        (ptr) = &(array)[__z_name_find_id];\
        break;\
      }\
} while(0)
