Method Detail

write

void write(Cache.Entry<K,V> entry)
Write the specified value under the specified key to the underlying store. This method is intended to support both key/value creation and value update for a specific key.

Parameters:
entry - the entry to be written
Throws:
CacheException - if ????? TODO describe when

writeAll

void writeAll(Collection<Cache.Entry<? extends K,? extends V>> entries)
Write the specified entries to the underlying store. This method is intended to support both insert and update. If this operation fails (by throwing an exception) after a partial success, the convention is that entries which have been written successfully are to be removed from the specified entries, indicating that the write operation for the entries left in the map has failed or has not been attempted.

Parameters:
entries - the entries to be written
Throws:
CacheException - if ????? TODO describe when

delete

void delete(Object key)
Delete the cache entry from the store

Parameters:
key - the key that is used for the delete operation
Throws:
CacheException - if ????? TODO describe when

deleteAll

void deleteAll(Collection<?> entries)
Remove data and keys from the underlying store for the given collection of keys, 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 keys, indicating that the erase operation for the keys left in the collection has failed or has not been attempted.

Parameters:
entries - the entries that have been removed from the cache
Throws:
CacheException - if ????? TODO describe when
