Constructor Detail

WrapperBinaryStore

public WrapperBinaryStore(BinaryStore store)

Construct a WrapperBinaryStore.

Parameters:

store - the BinaryStore to delegate to

Method Detail

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 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

toString

public String toString()

Returns a string representation of the object.

Overrides:

toString in class Object

Returns:

a string representation of the object

getBinaryStore

public BinaryStore getBinaryStore()

Returns:

the wrapped BinaryStore; null after it is destroyed

setBinaryStore

protected void setBinaryStore(BinaryStore store)

Specify the store to wrap. The store is set to null if/when this wrapper destroys it.

Parameters:

store - the wrapped BinaryStore

getSize

public int getSize()

Returns:

the number of keys in the wrapped BinaryStore

getBinaryStoreKeyMap

protected Map getBinaryStoreKeyMap()

Returns:

the map of keys stored by the wrapped BinaryStore

isCurrent

public boolean isCurrent()

Returns:

true if the page is still current

close

protected void close()

Used to specify that the page is no longer current.

checkDestroy

protected void checkDestroy()

Test if the underlying store can be destroyed, and if so, destroy it.

destroy

protected void destroy()

Destroy the underlying BinaryStore.
