Constructor Detail

JdkStore

public JdkStore(Map<K,V> map)

Create a new JdkStore backed by the given Map. Operations on the map must be thread-safe.

Parameters:

map - the map to back this store

JdkStore

public JdkStore(boolean persist)

Create a new JdkStore using a default backing Map, like ConcurrentHashMap.

Parameters:

persist - whether this store is expected to hold onto the stored values indefinitely. Will use a ConcurrentHashMap as backing if true, and a thread-safe WeakHashMap otherwise.
