DataCache(TKey, TValue) Class

DataCache TKey, TValue Class

TIBCO Spotfire 6.0 API Reference

DataCache TKey, TValue provides caching functionality for objects of different types, see list below. Since the size of the stored objects need to be known to be able to trim the cache size, only a selected subset of types are allowed to be stored.
Objects can be removed from the cache in one of the following situations:
- An object is explicitly removed through a call to Remove(TKey).
- An object has not been fetched within a certain time period. This time period is controlled through a setting.
- The system is running low on memory and therefore the cache is reduced in size.
The owner of the cache is responsible for providing unique keys for each object to store in the cache.
