Method Detail

createMap

ConcurrentMap<K,? extends TCacheHolder<V>> createMap(Builder<K,V> builder,
                                                     double sizeFactor)

Returns a ConcurrentMap conforming to the configuration specified in the builder. The sizeFactor is a hint that the Map should be sized bigger due to the Cache implementation. For example if eviction starts at 95% fill rate, sizeFactor could be 1 - 1/0.95 = 0,0526316

Parameters:

builder - The configuration parameter for the Map

sizeFactor - Sizing factor to take into account

Returns:

An instance of the storage.
