Types in this directory are used to populate a CookiesTreeModel
;
see //chrome/browser/browsing_data.
Instances of this type are used to fully populate a CookiesTreeModel
with full details (e.g. origin/size/modified) for different storage
types, e.g. to report storage used by all origins.
When StartFetching()
is called, a call is made into the relevant
storage context to enumerate usage info - usually, a set of tuples of
(origin, size, last modified). The CookiesTreeModel assembles this
into the tree of nodes used to populate UI.
Some UI also uses this to delete origin data, which again calls into the storage context.
Note that despite the name ("canned"), this is not a test-only type.
Subclass of the above. These are created to sparsely populate a
CookiesTreeModel
on demand by LocalSharedObjectContainer
, with
only some details (e.g. full details for cookies, but only the usage
of other storage typess).
PageSpecificContentSettings
is notified on storage access/blocked.- It calls into the "canned" helper instance for the storage type.
- The "canned" instance records necessary "pending" info about the access.
- On demand, the "pending" info is used to populate a CookiesTreeModel.
This "pending" info only needs to record the origin for most storage types.
Mock class for testing, only.
Adds an AddXYZSamples()
method that populates the instance with
test data.
