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