/* A higher-order macro for enumerating all JSProtoKey values. */

/*

 * Consumers define macros as follows:

 * MACRO(name, clasp)

 *   name:    The canonical name of the class.

 *   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.
