Method Detail

isSwapped

boolean isSwapped()

The cache sets it to true when the entry is swapped away. You should not write on a swapped away entry as those changes are lost. For 'ram' or 'jdbc' implementation this flag is not used and remains the initial value (set it to false in your implementation of I_MapEntry).

isSwapped

void isSwapped(boolean isSwapped)

Used by the cache implementation to mark entries which will be swapped to the persistent store.

getUniqueIdStr

java.lang.String getUniqueIdStr()

Returns:

The unique ID as a string (cached for performance)

getSortTimestamp

Timestamp getSortTimestamp()

Can be used by cache implementation to implement LRU

setSortTimestamp

void setSortTimestamp(Timestamp timstamp)

Can be used by cache implementation to implement LRU

getStorageId

StorageId getStorageId()

Must be filled if retrieved from database.

Returns:

can be null
