A load group maintains a collection of nsIRequest objects.
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.
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.
The group observer is notified when requests are added to and removed
from this load group. The groupObserver is weak referenced.
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.
Returns the requests contained directly in this group.
Enumerator element type: nsIRequest.
Returns the count of “active” requests (ie. requests without the
LOAD_BACKGROUND bit set).
Notification callbacks for the load group.
Connection information for managing things like js/css
connection blocking, and per-tab connection grouping
The set of load flags that will be added to all new requests added to
this group. Any existing requests in the load group are not modified,
so it is expected these flags will be added before requests are added
to the group - typically via nsIDocShell::defaultLoadFlags on a new
docShell.
Note that these flags are not added to the default request for the
load group; it is expected the default request will already have these
flags (again, courtesy of setting nsIDocShell::defaultLoadFlags before
the docShell has created the default request.)
