|
/* 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.
