Method overview

void addRequest(in nsIRequest aRequest, in nsISupports aContext);

Attributes

Attribute Type Description
activeCount unsigned long Returns the count of "active" requests (that is requests without the LOAD_BACKGROUND bit set). Read only.
defaultLoadRequest nsIRequest

Accesses the default load request for the group. Each time a number of requests are added to a group, the defaultLoadRequest may be set to indicate that all of the requests are related to a base request.

The load group inherits its load flags from the default load request. If the default load request is null, then the group's load flags are not changed.
groupObserver nsIRequestObserver The group observer is notified when requests are added to and removed from this load group. The groupObserver is weak referenced.
notificationCallbacks nsIInterfaceRequestor Notification callbacks for the load group.
requests nsISimpleEnumerator Returns the requests contained directly in this group. Enumerator element type: nsIRequest. Read only.

Methods

addRequest()

Adds a new request to the group. This will cause the default load flags to be applied to the request. If this is a foreground request then the groupObserver's onStartRequest will be called.

If the request is the default load request or if the default load request is null, then the load group will inherit its load flags from the request.

void addRequest(
  in nsIRequest aRequest,
  in nsISupports aContext
);
Parameters
aRequest
The request to be added to the load group.
aContext
The context to be passed to the onStartRequest notification.

removeRequest()

Removes a request from the group. If this is a foreground request then the groupObserver's onStopRequest will be called.

By the time this call ends, aRequest will have been removed from the loadgroup, even if this function throws an exception.

void removeRequest(
  in nsIRequest aRequest,
  in nsISupports aContext,
  in nsresult aStatus
);
Parameters
aRequest
The request to be removed from the load group.
aContext
The context to be passed to the onStopRequest notification.
aStatus
The status to be passed to the onStopRequest notification.
