java.lang.Object

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

All Implemented Interfaces:

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

public class InMemoryMessageListStore<K,M extends PMessage<M,F>,F extends PField>
extends Object
implements MessageListStore<K,M,F>

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

Look up a set of keys from the storage.

Specified by:

getAll in interface ReadOnlyStore<K,List<M extends PMessage<M,F>>>

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,List<M extends PMessage<M,F>>>

Parameters:

key - The key to look up.

Returns:

True if the key was contained in the map.

keys

@Nonnull
public Collection<K> keys()

Description copied from interface: ReadOnlyStore

Get a collection of all the keys in the store.

Specified by:

Returns:

Key collection.

putAll

@Nonnull
public Map<K,List<M>> putAll(@Nonnull
                                      Map<K,List<M>> values)

Specified by:

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

Parameters:

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

Returns:

Immutable map of replaced values. Values not already present should not have an entry in the result map (no key -> null mapping).

removeAll

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

Description copied from interface: ReadWriteStore

Remove the values for the given keys.

Specified by:

removeAll in interface ReadWriteStore<K,List<M extends PMessage<M,F>>>

Parameters:

keys - Map of removed key value pairs.

Returns:

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