10 /* A higher-order macro for enumerating all JSProtoKey values. */
11 /*
12 * Consumers define macros as follows:
13 * MACRO(name, clasp)
14 * name: The canonical name of the class.
15 * clasp: The JSClass for this object, or "dummy" if it doesn't exist.
16 *
17 *
18 * Consumers wishing to iterate over all the JSProtoKey values, can use
19 * JS_FOR_EACH_PROTOTYPE. However, there are certain values that don't
20 * correspond to real constructors, like Null or constructors that are disabled
21 * via preprocessor directives. We still need to include these in the JSProtoKey
22 * list in order to maintain binary XDR compatibility, but we need to provide a
23 * tool to handle them differently. JS_FOR_PROTOTYPES fills this niche.
24 *
25 * Consumers pass two macros to JS_FOR_PROTOTYPES - |REAL| and |IMAGINARY|. The
26 * former is invoked for entries that have real client-exposed constructors, and
27 * the latter is called for the rest. Consumers that don't care about this
28 * distinction can simply pass the same macro to both, which is exactly what
29 * JS_FOR_EACH_PROTOTYPE does.
