Constructor Detail

BinaryMapStore

public BinaryMapStore(BinaryMap map)

Construct a BinaryMapStore object, which is an implementation of the BinaryStore interface backed by a BinaryMap.

Parameters:

map - the BinaryMap to use for storage for this BinaryStore implementation

Method Detail

getBinaryMap

public BinaryMap getBinaryMap()

Obtain the underlying BinaryMap.

Returns:

the BinaryMap that this BinaryStore sits on top of

load

public Binary load(Binary binKey)

Return the value associated with the specified key, or null if the key does not have an associated value in the underlying store.

Specified by:

load in interface BinaryStore

Parameters:

binKey - key whose associated value is to be returned

Returns:

the value associated with the specified key, or null if no value is available for that key

store

public void store(Binary binKey,
                  Binary binValue)

Store the specified value under the specific key in the underlying store. This method is intended to support both key/value creation and value update for a specific key.

Specified by:

store in interface BinaryStore

Parameters:

binKey - key to store the value under

binValue - value to be stored

erase

public void erase(Binary binKey)

Remove the specified key from the underlying store if present.

Specified by:

erase in interface BinaryStore

Parameters:

binKey - key whose mapping is to be removed from the map

eraseAll

public void eraseAll()

Remove all data from the underlying store.

Specified by:

eraseAll in interface BinaryStore

keys

public java.util.Iterator keys()

Iterate all keys in the underlying store.

Specified by:

keys in interface BinaryStore

Returns:

a read-only iterator of the keys in the underlying store

size

public int size()

Determine the number of keys in the BinaryStore.

Specified by:

size in interface BinaryStore.SizeAware

Returns:

the number of keys in the BinaryStore

dispose

public void dispose()

close

public void close()

Deprecated. use the Disposable interface instead

Release underlying resources.
