public class BlindCompactSerializationCache

extends CompactSerializationCache

BlindCompactSerializationCache is a CompactSerializationCache extension enforcing CompactSerializationCache to operate under a blind mode.

Blind mode allows a Map implementation to forgo the often costly parts of the Map API, in particular returning the previous value for both remove and put operations. Additionally, any MapEvents raised as a result of mutations to this map will indiscriminately return null as the OldValue.

BlindCompactSerializationCache

public BlindCompactSerializationCache(BinaryStoreManager mgr,
                                      java.lang.ClassLoader loader)

Construct a BlindCompactSerializationCache using the specified BinaryStoreManager and classloader.

Parameters:

mgr - the BinaryStoreManager to use to create the BinaryStore

loader - the ClassLoader to use for deserialization

BlindCompactSerializationCache

public BlindCompactSerializationCache(BinaryStoreManager mgr,
                                      boolean fBinary)

Construct a BlindCompactSerializationCache using the specified BinaryStoreManager, optionally storing only Binary keys and values

Parameters:

mgr - the BinaryStoreManager to use to create the BinaryStore

fBinary - true iff only Binary keys and values are to be stored

BlindCompactSerializationCache

protected BlindCompactSerializationCache(BinaryStoreManager mgr,
                                         java.lang.ClassLoader loader,
                                         boolean fBinary)

Method Detail

isBlind

public boolean isBlind()

Return whether this CompactSerializationCache instance is in blind mode. Blind mode allows this Map implementation to forgo the often costly parts of the Map API, in particular returning the previous value for both remove and put operations.

Overrides:

isBlind in class CompactSerializationCache

Returns:

whether this CompactSerializationCache is operating in a blind mode
