nsIApplicationCache in Firefox 3.6a1pre

 Application caches store resources for offline use.  Each
 application cache has a unique client ID for use with
 nsICacheService::openSession() to access the cache's entries.

 Each entry in the application cache can be marked with a set of
 types, as discussed in the WHAT-WG offline applications
 specification.

 All application caches with the same group ID belong to a cache
 group.  Each group has one "active" cache that will service future
 loads.  Inactive caches will be removed from the cache when they are
 no longer referenced.

Constants

 Entries in an application cache can be marked as one or more of
 the following types.

const unsigned long ITEM_MANIFEST = 1

const unsigned long ITEM_EXPLICIT = 2

const unsigned long ITEM_IMPLICIT = 4

const unsigned long ITEM_DYNAMIC = 8

const unsigned long ITEM_FOREIGN = 16

const unsigned long ITEM_FALLBACK = 32

const unsigned long ITEM_OPPORTUNISTIC = 64

Attributes

 TRUE if the cache is the active cache for this group.

readonly attribute boolean active

 The client ID for this application cache.  Clients can open a
 session with nsICacheService::createSession() using this client
 ID and a storage policy of STORE_OFFLINE to access this cache.

readonly attribute ACString clientID

 The group ID for this cache group.  This is the URI of the
 manifest file.

readonly attribute ACString groupID

 The disk usage of the application cache, in bytes.

readonly attribute unsigned long usage

Methods

 Makes this cache the active application cache for this group.
 Future loads associated with this group will come from this
 cache.  Other caches from this cache group will be deactivated.

void activate()

 Add a set of namespace entries to the application cache.
 @param namespaces
        An nsIArray of nsIApplicationCacheNamespace entries.

void addNamespaces(in nsIArray namespaces)

 Discard this application cache.  Removes all cached resources
 for this cache.  If this is the active application cache for the
 group, the group will be removed.

void discard()

 Returns any entries in the application cache whose type matches
 one or more of the bits in typeBits.

void gatherEntries(in PRUint32 typeBits, out unsigned long count, [array, size_is(count)] out string keys)

 Get the most specific namespace matching a given key.

nsIApplicationCacheNamespace getMatchingNamespace(in ACString key)

 Gets the types for a given entry.

unsigned long getTypes(in ACString key)

 Adds item types to a given entry.

void markEntry(in ACString key, in unsigned long typeBits)

 Removes types from a given entry.  If the resulting entry has
 no types left, the entry is removed.

void unmarkEntry(in ACString key, in unsigned long typeBits)
