Package net.morimekta.providence.storage

Class InMemoryMessageListStore<K,M extends 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,java.util.List<M>>, ReadWriteStore<K,java.util.List<M>>

public class InMemoryMessageListStore<K,M extends PMessage<M>>
extends java.lang.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 java.util.Map<K,java.util.List<M>> getAll(@Nonnull
                                                       java.util.Collection<K> keys)

Description copied from interface: ReadOnlyStore

Look up a set of keys from the storage.

Specified by:

getAll in interface ReadOnlyStore<K,M extends 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).

containsKey

public boolean containsKey(@Nonnull
                           K key)

Specified by:

containsKey in interface ReadOnlyStore<K,M extends PMessage<M>>

Parameters:

key - The key to look up.

Returns:

True if the key was contained in the map.

keys

@Nonnull

putAll

public void putAll(@Nonnull
                   java.util.Map<K,java.util.List<M>> values)

Specified by:

putAll in interface ReadWriteStore<K,M extends PMessage<M>>

Parameters:

values - Put all key value pairs form this map into the storage.

removeAll
