#ifndef js_ProtoKey_h

/* A higher-order macro for enumerating all JSProtoKey values. */
/*
* Consumers define macros as follows:
* macro(name, init, clasp)
* name: The canonical name of the class.
* 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.
