Class InMemoryMessageListStore<K,M extends net.morimekta.providence.PMessage<M>>

java.lang.Object

net.morimekta.providence.storage.InMemoryMessageListStore<K,M>

Type Parameters:

K - The key type.

M - The stored message type.

All Implemented Interfaces:

MessageListReadOnlyStore<K,M>, MessageListStore<K,M>, ReadOnlyStore<K,List<M>>, ReadWriteStore<K,List<M>>

public class InMemoryMessageListStore<K,M extends net.morimekta.providence.PMessage<M>>
extends Object
implements MessageListStore<K,M>

Simple in-memory storage of lists providence messages. Uses a local hash map for storing the instances.The store is thread safe through using reentrand read-write mutex handling, so reading can happen in parallel.

Method Detail

getAll

@Nonnull
public Map<K,List<M>> getAll(@Nonnull
                                      Collection<K> keys)

Description copied from interface: ReadOnlyStore

getAll in interface ReadOnlyStore<K,List<M extends net.morimekta.providence.PMessage<M>>>

Parameters:

keys - The keys to look up.

Returns:

Map of all the found key value pairs. Values not found should not have an entry in the result map (no key -> null mapping).
