Description copied from interface: StoreService

This is called to provide a new store instance for the provided configuration.

Specified by:

provideGenericStore in interface StoreService

Type Parameters:

K - The key type which provides a 1:1 mapping to the value type. This type is also expected to be Comparable in order to allow for range operations.

V - The value type, these follow JavaBean conventions.

keyClass - The class of the keys.

valueClass - The class of the values.

Returns:

The instance of the store.

This is used to check if this service can provide long-object stores.

Specified by:

hasLongObjStores in interface StoreService

Returns:

True if possible, else false.

provideLongObjStore

public <V> LongObjStore<V> provideLongObjStore(Class<V> valueClass)

Description copied from interface: StoreService

This is called to provide a new store instance with a long key and object values.

Specified by:

provideLongObjStore in interface StoreService

Type Parameters:

V - The value type, these follow JavaBean conventions.

Parameters:

valueClass - The class of the values.

Returns:

The instance of the store.

init

public void init(StoreContext context)

Description copied from interface: StoreService

This is a lifecycle method called to signal that a store should allocate any necessary resources.

Specified by:

init in interface StoreService
