| cern::gp::nodes::cache::TimeLimitedCachingStrategy::TimeLimitedCachingStrategy | ( | int | timeoutMillis | ) | [inline] |
Constructs a new caching strategy based on the given time
- Parameters:
-
timeoutMillis the timeout for the cache
Member Function Documentation
| void cern::gp::nodes::cache::TimeLimitedCachingStrategy::invalidateCache | ( | ) | [inline] |
Invalidates the current cached value. This method is called to signal that the cached value should not be used anymore.
Implements cern::gp::nodes::cache::CachingStrategy.
References lastAccessTimeMillis.
| boolean cern::gp::nodes::cache::TimeLimitedCachingStrategy::isCacheValid | ( | ) | [inline] |
Checks whether the cache is still valid. If true is returned the cached value will be used. If false is returned the cached value will be discarded and the getter will be invoked to get a new value.
- Returns:
- true if the cache is still valid

| void cern::gp::nodes::cache::TimeLimitedCachingStrategy::validateCache | ( | ) | [inline] |
Validates the current cached value. This method is called to signal that the cached value has just been updated. The strategy should take this event into account for the implementation of isCached()
