/**
|
|
* Class to store the wrapper for an object. This can only be used with objects
|
|
* that only have one non-security wrapper at a time (for an XPCWrappedNative
|
|
* this is usually ensured by setting an explicit parent in the PreCreate hook
|
|
* for the class).
|
|
*
|
|
* An instance of nsWrapperCache can be gotten from an object that implements
|
|
* a wrapper cache by calling QueryInterface on it. Note that this breaks XPCOM
|
|
* rules a bit (this object doesn't derive from nsISupports).
|
|
*
|
|
* The cache can store objects other than wrappers. We allow wrappers to use a
|
|
* separate JSObject to store their state (mostly expandos). If the wrapper is
|
|
* collected and we want to preserve this state we actually store the state
|
|
* object in the cache.
|
|
*
|
|
* The cache can store 2 types of objects:
|
|
*
|
|
* If WRAPPER_IS_DOM_BINDING is not set (IsDOMBinding() returns false):
|
|
* - a slim wrapper or the JSObject of an XPCWrappedNative wrapper
|
|
*
|
|
* If WRAPPER_IS_DOM_BINDING is set (IsDOMBinding() returns true):
|
|
* - a DOM binding object (regular JS object or proxy)
|
|
*
|
|
* The finalizer for the wrapper clears the cache.
|
|
*
|
|
* A number of the methods are implemented in nsWrapperCacheInlines.h because we
|
|
* have to include some JS headers that don't play nicely with the rest of the
|
|
* codebase. Include nsWrapperCacheInlines.h if you need to call those methods.
