public interface BinaryEntryStore
BinaryEntryStore is analogous to the CacheStore
, but operates on BinaryEntry
objects. Note that the BinaryEntry interface extends Map.Entry and provides dual access to the underlying data: in external (Object) format via the getKey/getValue/setValue methods or internal (Binary) format via getBinaryKey/getBinaryValue/updateBinaryValue methods. Additionally, for the purpose of the optimistic concurrency control, implementations could rely on the entry's "previous" values: in the external format using BinaryEntry.getOriginalValue()
and in the internal format using the BinaryEntry.getOriginalBinaryValue()
methods (for store operations, a value of null here would indicate an insert operation).

Method Detail |

void load(BinaryEntry binEntry)
binEntry
- an entry that needs to be updated with the loaded valuevoid loadAll(java.util.Set setBinEntries)
setBinEntries
- a set of entries that needs to be updated with the loaded valuesvoid store(BinaryEntry binEntry)
If the store operation changes the entry's value, a best effort will be made to place the changed value back into the corresponding backing map (for asynchronous store operations a concurrent backing map modification can make it impossible).
binEntry
- the entry to be storedjava.lang.UnsupportedOperationException
- if this implementation or the underlying store is read-onlyvoid storeAll(java.util.Set setBinEntries)
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 set, indicating that the store operation for the entries left in the map has failed or has not been attempted.
If the storeAll operation changes some entries' values, a best effort will be made to place the changed values back into the corresponding backing map (for asynchronous store operations concurrent backing map modifications can make it impossible).
setBinEntries
- the set of entries to be storedjava.lang.UnsupportedOperationException
- if this implementation or the underlying store is read-onlyvoid erase(BinaryEntry binEntry)
binEntry
- the entry to be removed from the storejava.lang.UnsupportedOperationException
- if this implementation or the underlying store is read-onlyvoid eraseAll(java.util.Set setBinEntries)
If this operation fails (by throwing an exception) after a partial success, the convention is that entries which have been erased successfully are to be removed from the specified set, indicating that the erase operation for the entries left in the collection has failed or has not been attempted.
setBinEntries
- the set entries to be removed from the storejava.lang.UnsupportedOperationException
- if this implementation or the underlying store is read-only
