Interface ICacheEntryValidity
- All Known Implementing Classes:
AlwaysValidCacheEntryValidity
,NonCacheableCacheEntryValidity
,TTLCacheEntryValidity
Common interface for all objects defining the validity of a template resolution.
These objects are queried by the Template Cache for knowing whether a template is cacheable or not, and also for determining if an existing cache entry is still valid.
A typical implementation is TTLCacheEntryValidity
,
which determines the validity of a cache entry based on a TTL (time-to-live).
