1.13 +/* A higher-order macro for enumerating all JSProtoKey values. */
1.14 +/*
1.15 + * Consumers define macros as follows:
1.16 + * macro(name, code, init, clasp)
1.17 + * name: The canonical name of the class.
1.18 + * code: The enumerator code. There are part of the XDR API, and must not change.
1.19 + * init: Initialization function. These are |extern "C";|, and clients should use
1.20 + * |extern "C" {}| as appropriate when using this macro.
1.21 + * clasp: The JSClass for this object, or "dummy" if it doesn't exist.
1.22 + *
1.23 + *
1.24 + * Consumers wishing to iterate over all the JSProtoKey values, can use
1.25 + * JS_FOR_EACH_PROTOTYPE. However, there are certain values that don't correspond
1.26 + * to real constructors, like Null or constructors that are disabled via
1.27 + * preprocessor directives. We still need to include these in the JSProtoKey list
1.28 + * in order to maintain binary XDR compatibility, but we need to provide a tool
1.29 + * to handle them differently. JS_FOR_PROTOTYPES fills this niche.
1.30 + *
1.31 + * Consumers pass two macros to JS_FOR_PROTOTYPES - |real| and |imaginary|. The
1.32 + * former is invoked for entries that have real client-exposed constructors, and
1.33 + * the latter is called for the rest. Consumers that don't care about this
1.34 + * distinction can simply pass the same macro to both, which is exactly what
1.35 + * JS_FOR_EACH_PROTOTYPE does.
