Implementations serve as caches for historical or reference data retrieved
via lookup keys consisting or one or more rows represented by a list of events.
The following tables list the members exposed by the DataCache type.
Public Methods
Name | Description | |
---|---|---|
![]() | GetCached | Ask the cache if the keyed value is cached, returning a list or rows if the key is in the cache,
or returning null to indicate no such key cached. Zero rows may also be cached.
|
![]() | PutCached | Puts into the cache a key and a list of rows, or an empty list if zero rows.
The put method is designed to be called when the cache does not contain a key as determined by the get method. Implementations typically simply overwrite any keys put into the cache that already existed in the cache. |
