Support for caching a function with synchronized cache miss support.

Method Summary

Modifier and Type	Method and Description
V	get(K cacheKey, Function<K,V> fallbackLoaderFunction, Function<K,XPFCacheResult<V>> checkCacheFunction, BiFunction<K,V,V> populateCacheFunction) Get the requested key from the cache, or use the fallback loader function if the key is not present.

Method Detail

get

V get(K cacheKey,
      Function<K,V> fallbackLoaderFunction,
      Function<K,XPFCacheResult<V>> checkCacheFunction,
      BiFunction<K,V,V> populateCacheFunction)

Get the requested key from the cache, or use the fallback loader function if the key is not present. In the case of a miss, this method will cache the result of the fallback loader execution, ensuring that the cache population function is only invoked once per cache miss for a particular cache key.

Parameters:

cacheKey - the cache key object

fallbackLoaderFunction - the function for populating the cache

checkCacheFunction - the function for retrieving the passed key from the cache

populateCacheFunction - the function for populating the cache with the passed key and value

Returns:

the result
