Parameters

key

Type: SystemString
The key.

refreshCallback

Type: SystemFuncT
A function which returns a new value for the specified key, or if no update function available (see remarks).

forceCacheRefresh (Optional)

Type: SystemBoolean
If , the value associated with key will be always be refreshed by calling refreshCallback, even if a value is already cached.

Return Value

• The cache does not contain any value associated with key.
• forceCacheRefresh is .
• The previously cached value for key is no longer valid. The exact algorithm for determining whether or not a value is valid in implementation-defined.

If any of the above conditions is met and refreshCallback is , the previously cached value for key, if any, is removed from the cache and the default value for T is returned.
