Changeset 15462 in webkit for trunk/JavaScriptCore/API/JSClassRef.cpp

Timestamp:

Message:

Reviewed by Maciej.

• Moved the arguments passed to JSClassCreate into a single structure, called JSClassDefinition. This will enable easier structure migration/versioning in the future, if necessary.

• Added support for class names.

• kJSClassDefinitionNull replaces kJSObjectCallbacksNone.

• JSClass is becoming a fairly complex struct, so I migrated all of its implementation other than reference counting to the sruct.

• Also moved JSClass* functions in the API to JSObjectRef.cpp, since they're declared in JSObjectRef.h

• Also added some more informative explanation to the class structure doc.
