Method Detail

getCrudRepository

public org.springframework.data.repository.CrudRepository getCrudRepository()

setCrudRepository

public void setCrudRepository(org.springframework.data.repository.CrudRepository crudRepository)

store

public void store(Serializable key,
                  Object value)

Description copied from interface: MapStore

Stores the key-value pair. If an exception is thrown then the put operation will fail.

Specified by:

store in interface MapStore<Serializable,Object>

Parameters:

key - key of the entry to store

value - value of the entry to store

storeAll

public void storeAll(Map map)

Description copied from interface: MapStore

Stores multiple entries. Implementation of this method can optimize the store operation by storing all entries in one database connection for instance. storeAll used when writeDelaySeconds is positive (write-behind). If an exception is thrown the entries will be tried to be stored one by one using store() method.

Specified by:

storeAll in interface MapStore<Serializable,Object>

Parameters:

map - map of entries to store

delete

public void delete(Serializable key)

Description copied from interface: MapStore

Deletes the entry with a given key from the store. If an exception is thrown the remove operation will fail.

Specified by:

delete in interface MapStore<Serializable,Object>

Parameters:

key - key to delete from the store.

load

public Object load(Serializable key)

Description copied from interface: MapLoader

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 MapLoader<Serializable,Object>

Returns:

value of the key

deleteAll

public void deleteAll(Collection keys)

Description copied from interface: MapStore

Deletes multiple entries from the store. If an exception is thrown the entries will be tried to be deleted one by one using delete() method.

Specified by:

deleteAll in interface MapStore<Serializable,Object>

Parameters:

keys - keys of the entries to delete.

loadAll

public Map loadAll(Collection collection)

Description copied from interface: MapLoader

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

Specified by:

loadAll in interface MapLoader<Serializable,Object>

Parameters:

collection - keys of the values entries to load

Returns:

map of loaded key-value pairs.

loadAllKeys

public Set loadAllKeys()

Description copied from interface: MapLoader

Loads all of the keys from the store.

Specified by:

loadAllKeys in interface MapLoader<Serializable,Object>

Returns:

all the keys
