This interface represents an application cache namespace.

Application caches can store a set of namespace entries that affect loads from the application cache. If a load from the cache fails to match on an exact cache entry, the namespace entries are searched for a substring match.

Method overview

void init(in unsigned long itemType, in ACString namespaceSpec, in ACString data);

Attributes

Attribute	Type	Description
`data`	`ACString`	Data associated with the namespace, such as a fallback. How this attribute is used varies depending on the namespace type. If the data is a URI, this attribute should be the URI's `asciiSpec`. Read only.
`itemType`	`unsigned long`	A bit field indicating one or more namespace types. Must be one or more of the constants defined under Constants on this page. Read only.
`namespaceSpec`	`ACString`	The prefix of this namespace. This should be the `asciiSpec` of the URI prefix. Read only.

Constants

Constant	Value	Description
`NAMESPACE_BYPASS`	`1`	Items matching this namespace can be fetched from the network when loading from this cache. The `data` attribute is not used.
`NAMESPACE_FALLBACK`	`2`	Items matching this namespace can be fetched from the network when loading from this cache; however, if the load fails, the cache entry specified by the `data` attribute should be loaded intstead.
`NAMESPACE_OPPORTUNISTIC`	`4`	Items matching this namespace should be cached opportunistically. Successful top-level loads of resources in this namespace should be placed into the application cache. This can be combined with `NAMESPACE_FALLBACK` to provide a fallback entry in the `data` attribute.

Methods

init()

Initializes the namespace.

void init(
  in unsigned long itemType,
  in ACString namespaceSpec,
  in ACString data
);

Parameters

itemType: The namespace type.
namespaceSpec: The namespace's prefix.
data: The data to associate with the namespace.
