/**
|
|
* Create a remote debugging protocol root actor.
|
|
*
|
|
* @param aConnection
|
|
* The DebuggerServerConnection whose root actor we are constructing.
|
|
*
|
|
* @param aParameters
|
|
* The properties of |aParameters| provide backing objects for the root
|
|
* actor's requests; if a given property is omitted from |aParameters|, the
|
|
* root actor won't implement the corresponding requests or notifications.
|
|
* Supported properties:
|
|
*
|
|
* - tabList: a live list (see below) of tab actors. If present, the
|
|
* new root actor supports the 'listTabs' request, providing the live
|
|
* list's elements as its tab actors, and sending 'tabListChanged'
|
|
* notifications when the live list's contents change. One actor in
|
|
* this list must have a true '.selected' property.
|
|
*
|
|
* - addonList: a live list (see below) of addon actors. If present, the
|
|
* new root actor supports the 'listAddons' request, providing the live
|
|
* list's elements as its addon actors, and sending 'addonListchanged'
|
|
* notifications when the live list's contents change.
|
|
*
|
|
* - globalActorFactories: an object |A| describing further actors to
|
|
* attach to the 'listTabs' reply. This is the type accumulated by
|
|
* DebuggerServer.addGlobalActor. For each own property |P| of |A|,
|
|
* the root actor adds a property named |P| to the 'listTabs'
|
|
* reply whose value is the name of an actor constructed by
|
|
* |A[P]|.
|
|
*
|
|
* - onShutdown: a function to call when the root actor is disconnected.
|
|
*
|
|
* Instance properties:
|
|
*
|
|
* - applicationType: the string the root actor will include as the
|
|
* "applicationType" property in the greeting packet. By default, this
|
|
* is "browser".
|
|
*
|
|
* Live lists:
|
|
*
|
|
* A "live list", as used for the |tabList|, is an object that presents a
|
|
* list of actors, and also notifies its clients of changes to the list. A
|
|
* live list's interface is two properties:
|
|
*
|
|
* - getList: a method that returns a promise to the contents of the list.
|
|
*
|
|
* - onListChanged: a handler called, with no arguments, when the set of
|
|
* values the iterator would produce has changed since the last
|
|
* time 'iterator' was called. This may only be set to null or a
|
|
* callable value (one for which the typeof operator returns
|
|
* 'function'). (Note that the live list will not call the
|
|
* onListChanged handler until the list has been iterated over
|
|
* once; if nobody's seen the list in the first place, nobody
|
|
* should care if its contents have changed!)
|
|
*
|
|
* When the list changes, the list implementation should ensure that any
|
|
* actors yielded in previous iterations whose referents (tabs) still exist
|
|
* get yielded again in subsequent iterations. If the underlying referent
|
|
* is the same, the same actor should be presented for it.
|
|
*
|
|
* The root actor registers an 'onListChanged' handler on the appropriate
|
|
* list when it may need to send the client 'tabListChanged' notifications,
|
|
* and is careful to remove the handler whenever it does not need to send
|
|
* such notifications (including when it is disconnected). This means that
|
|
* live list implementations can use the state of the handler property (set
|
|
* or null) to install and remove observers and event listeners.
|
|
*
|
|
* Note that, as the only way for the root actor to see the members of the
|
|
* live list is to begin an iteration over the list, the live list need not
|
|
* actually produce any actors until they are reached in the course of
|
|
* iteration: alliterative lazy live lists.
