For each such interface, there # is a corresponding entry in the configuration table below. The configuration # table maps each interface name to a |descriptor| or list of |descriptor|s. # # Valid fields for all descriptors: # * nativeType - The native type (concrete class or XPCOM interface) that # instances of this interface will unwrap to. If not # specified, defaults to "mozilla::dom::InterfaceName" for # non-worker non-external-or-callback interfaces, to # "mozilla::dom::workers::InterfaceName" for worker # non-external interfaces, to 'nsIDOM' followed by the # interface name for non-worker external-or-callback # interfaces, and to "JSObject" for worker external-or-callback # interfaces. # * headerFile - The file in which the nativeType is declared (defaults # to an educated guess). # * castable - Indicates whether the value in the wrapper can be cast to # nativeType, or whether it needs to be QI-ed (defaults to True # for everything but callback interfaces and external interfaces, # for which it defaults to false and is not allowed to be set # at all). # * concrete - Indicates whether there exist objects with this interface as # their primary interface. Always False for callback interfaces. # defaults to True otherwise. # * prefable - Indicates whether this bindings should be disabled if the # global pref for Web IDL bindings is set to false. This is a # risk mitigation strategy and it will cause all of the Web IDL # bindings marked as prefable to fall back to the xpconnect # bindings in case something goes wrong. This defaults to False. # Setting this on objects which only have Web IDL bindings does # not make any sense. # Cannot be set on external interfaces. # * workers - Indicates whether the descriptor is intended to be used for # worker threads (defaults to false). # * customTrace - The native class will use a custom trace hook (defaults to # true for workers, false otherwise). # * customFinalize - The native class will use a custom finalize hook # (defaults to true for workers, false otherwise). # * notflattened - The native type does not have nsIClassInfo, so when # wrapping it the right IID needs to be passed in. # * register - True if this binding should be registered. Defaults to true. # * binaryNames - Dict for mapping method and attribute names to different # names when calling the native methods (defaults to an empty # dict). The keys are the property names as they appear in the # .webidl file and the values are the names as they should be # in the WebIDL. # * wrapperCache: True if this object is a wrapper cache. Objects that are # not can only be returned from a limited set of methods, # cannot be prefable, and must ensure that they disallow # XPConnect wrapping. Always false for callback interfaces. # Always true for worker descriptors for non-callback # interfaces. Defaults to true for non-worker non-callback # descriptors. # * nativeOwnership: Describes how the native object is held. 4 possible # types: worker object ("worker"), non-refcounted object # ("owned"), refcounted non-nsISupports object # ("refcounted") or nsISupports ("nsisupports"). # Non-refcounted objects need to inherit from # mozilla::dom::NonRefcountedDOMObject and preferably use # MOZ_COUNT_CTOR/MOZ_COUNT_DTOR in their # constructor/destructor so they participate in leak # logging. # This mostly determines how the finalizer releases the # binding's hold on the native object. For a worker object # it'll call Release, for a non-refcounted object it'll # call delete through XPConnect's deferred finalization # mechanism, for a refcounted object it'll call Release # through XPConnect's deferred finalization mechanism. # Always "worker" for worker descriptors. Defaults to # "nsisupports". # # The following fields are either a string, an array (defaults to an empty # array) or a dictionary with three possible keys (all, getterOnly and # setterOnly) each having such an array as the value # # * implicitJSContext - attributes and methods specified in the .webidl file # that require a JSContext as the first argument # * resultNotAddRefed - attributes and methods specified in the .webidl file # that do not AddRef the return value DOMInterfaces = { 'mozAudioContext': { 'nativeType': 'AudioContext', 'implicitJSContext': [ 'createBuffer' ],
