Method Detail

store

public void store(java.lang.Object oKey,
                  java.lang.Object oValue)
Store the specified value under the specified 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 CacheStore
Parameters:
oKey - key to store the value under
oValue - value to be stored
Throws:
java.lang.UnsupportedOperationException - if this implementation or the underlying store is read-only

storeAll

public void storeAll(java.util.Map mapEntries)
Store the specified values under the specified keys in the underlying store. This method is intended to support both key/value creation and value update for the specified keys.

The implementation of this method calls store(java.lang.Object, java.lang.Object) for each entry in the supplied Map. Once stored successfully, an entry is removed from the Map (if possible).

Note: For many types of persistent stores, a single store operation is as expensive as a bulk store operation; therefore, subclasses should override this method if possible.

Specified by:
storeAll in interface CacheStore
Parameters:
mapEntries - a Map of any number of keys and values to store
Throws:
java.lang.UnsupportedOperationException - if this implementation or the underlying store is read-only

erase

public void erase(java.lang.Object oKey)
Remove the specified key from the underlying store if present.
Specified by:
erase in interface CacheStore
Parameters:
oKey - key whose mapping is being removed from the cache
Throws:
java.lang.UnsupportedOperationException - if this implementation or the underlying store is read-only

eraseAll

public void eraseAll(java.util.Collection colKeys)
Remove the specified keys from the underlying store if present.

The implementation of this method calls erase(java.lang.Object) for each key in the supplied Collection. Once erased successfully, a key is removed from the Collection (if possible).

Note: For many types of persistent stores, a single erase operation is as expensive as a bulk erase operation; therefore, subclasses should override this method if possible.

Specified by:
eraseAll in interface CacheStore
Parameters:
colKeys - keys whose mappings are being removed from the cache
Throws:
java.lang.UnsupportedOperationException - if this implementation or the underlying store is read-only
