Method Detail

store

public void store(Long key,
                  Object value)

Description copied from interface: QueueStore

Stores the key-value pair.

Specified by:

store in interface QueueStore<Object>

Parameters:

key - key of the entry to store

value - value of the entry to store

storeAll

public void storeAll(Map<Long,Object> map)

Description copied from interface: QueueStore

Stores multiple entries. Implementation of this method can optimize the store operation by storing all entries in one database connection for instance.

Specified by:

storeAll in interface QueueStore<Object>

Parameters:

map - map of entries to store

delete

public void delete(Long key)

Description copied from interface: QueueStore

Deletes the entry with a given key from the store.

Specified by:

delete in interface QueueStore<Object>

Parameters:

key - key to delete from the store.

deleteAll

public void deleteAll(Collection<Long> keys)

Description copied from interface: QueueStore

Deletes multiple entries from the store.

Specified by:

deleteAll in interface QueueStore<Object>

Parameters:

keys - keys of the entries to delete.

load

public Object load(Long key)

Description copied from interface: QueueStore

Loads the value of a given key. If distributed map doesn't contain the value for the given key then Hazelcast will call implementation's load (key) method to obtain the value. Implementation can use any means of loading the given key; such as an O/R mapping tool, simple SQL or reading a file etc.

Specified by:

load in interface QueueStore<Object>

Returns:

value of the key

loadAll

public Map<Long,Object> loadAll(Collection<Long> keys)

Description copied from interface: QueueStore

Loads given keys. This is batch load operation so that implementation can optimize the multiple loads.

Specified by:

loadAll in interface QueueStore<Object>

Parameters:

keys - keys of the values entries to load

Returns:

map of loaded key-value pairs.

loadAllKeys

public Set<Long> loadAllKeys()

Description copied from interface: QueueStore

Loads all of the keys from the store.

Specified by:

loadAllKeys in interface QueueStore<Object>

Returns:

all the keys
