Method Detail

store

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.

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

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.

If this operation fails (by throwing an exception) after a partial success, the convention is that entries which have been stored successfully are to be removed from the specified mapEntries, indicating that the store operation for the entries left in the map has failed or has not been attempted.

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

void erase(java.lang.Object oKey)

Remove the specified key from the underlying store if present.

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

void eraseAll(java.util.Collection colKeys)

Remove the specified keys from the underlying store if present.

If this operation fails (by throwing an exception) after a partial success, the convention is that keys which have been erased successfully are to be removed from the specified colKeys, indicating that the erase operation for the keys left in the collection has failed or has not been attempted.

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
