Package net.morimekta.providence.storage.hazelcast

Class HazelcastMessageStorage<Key,Message extends PMessage<Message>>

java.lang.Object

net.morimekta.providence.storage.hazelcast.HazelcastMessageStorage<Key,Message>

All Implemented Interfaces:

MessageReadOnlyStore<Key,Message>, MessageStore<Key,Message>, ReadOnlyStore<Key,Message>, ReadWriteStore<Key,Message>

public class HazelcastMessageStorage<Key,Message extends PMessage<Message>>
extends java.lang.Object
implements MessageStore<Key,Message>

Note that the hazelcast message store is backed by the PMessage serializable property, which makes the message fields not indexable. If that is needed, use the HazelcastMessageBuilderStorage instead.

On the other hand, this type of map is somewhat more efficient, and does not require the message to be generated with hazelcast portable support.

public HazelcastMessageStorage(com.hazelcast.core.IMap<Key,Message> hazelcastMap)

Method Detail

putAll

public void putAll(@Nonnull
                   java.util.Map<Key,Message> values)

Specified by:

putAll in interface ReadWriteStore<Key,Message extends PMessage<Message>>

Parameters:

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

removeAll

@Nonnull
public void removeAll(java.util.Collection<Key> keys)

Description copied from interface: ReadWriteStore

Remove the values for the given keys.

Specified by:

removeAll in interface ReadWriteStore<Key,Message extends PMessage<Message>>

Parameters:

keys - Map of removed key value pairs.

getAll

@Nonnull
public java.util.Map<Key,Message> getAll(@Nonnull
                                               java.util.Collection<Key> keys)

Description copied from interface: ReadOnlyStore

Look up a set of keys from the storage.

Specified by:

getAll in interface ReadOnlyStore<Key,Message extends PMessage<Message>>

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
                           Key key)

Specified by:

containsKey in interface ReadOnlyStore<Key,Message extends PMessage<Message>>

Parameters:

key - The key to look up.

Returns:

True if the key was contained in the map.

keys

@Nonnull
public java.util.Collection<Key> keys()

Description copied from interface: ReadOnlyStore

Get a collection of all the keys in the store.

Specified by:

keys in interface ReadOnlyStore<Key,Message extends PMessage<Message>>

Returns:

Key collection.

size

public int size()

Specified by:

size in interface ReadOnlyStore<Key,Message extends PMessage<Message>>

Returns:

Get the total number of entries in the store, same as the number of unique keys.
