interface nsIAddonInterposition : nsISupports

/**
 * This interface allows Firefox to expose different implementations of its own
 * classes to add-ons. Once an interposition is created, it must be assigned to
 * an add-on using Cu.setAddonInterposition (JS) or xpc::SetAddonInterposition
 * (C++). In both cases, the arguments should be the add-on ID and the
 * interposition object (which must be an nsIAddonInterposition). This must
 * happen before any compartments are created for the given add-on.
 *
 * Every time the add-on accesses a property on any object outside its own set
 * of compartments, XPConnect will call the interposition's
 * interpose method. If the interposition wants to replace the given
 * property, it should return a replacement property descriptor for it. If not,
 * it should return null.

Methods

Trait Implementations

impl XpCom for nsIAddonInterposition

const IID: nsIID

IID: nsIID = nsID(3495740925, 44424, 16806, [133, 76, 54, 253, 148, 214, 157, 219])

fn query_interface<T: XpCom>(&self) -> Option<RefPtr<T>>

Perform a QueryInterface call on this object, attempting to dynamically cast it to the requested interface type. Returns Some(RefPtr) if the cast succeeded, and None otherwise.

impl RefCounted for nsIAddonInterposition

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIAddonInterposition

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
