Method Detail

memoryConsumptionBytes

public static final int memoryConsumptionBytes()

dataLength

public final long dataLength()

Description copied from interface: StorageEntity

the entity's data length, meaning the pure content length without any header or meta data.

Specified by:

dataLength in interface StorageEntity

Specified by:

dataLength in interface StorageEntityCacheItem<StorageEntity.Default>

typeId

public long typeId()

Description copied from interface: StorageEntity

The entity's type id.

Specified by:

typeId in interface StorageEntity

storagePosition

public final long storagePosition()

Specified by:

storagePosition in interface StorageEntityCacheItem<StorageEntity.Default>

cachedDataLength

public final long cachedDataLength()

Description copied from interface: StorageEntity

The length this entity occupies in the cache. This might be vary, even for fixed length typed, from the values returned by StorageEntity.dataLength() as only parts of an entity (e.g. only references) might be loaded into cache and because the cache might hold the header/meta data of an entity as well.

Specified by:

cachedDataLength in interface StorageEntity

hasReferences

public final boolean hasReferences()

Description copied from interface: StorageEntity

The information if this entity's type has reference fields (regardless of a particular entity's actual data).

Specified by:

hasReferences in interface StorageEntity

objectId

public final long objectId()

Description copied from interface: StorageEntity

The entity's biunique identifying id number.

Specified by:

objectId in interface StorageEntity

Specified by:

objectId in interface StorageEntityCacheItem<StorageEntity.Default>

lastTouched

public final long lastTouched()

Description copied from interface: StorageEntity

The approximate system time that this particular entity has been last touched. The returned value is compatible to the value returned by System.currentTimeMillis().

Specified by:

lastTouched in interface StorageEntity

storageFile

public final StorageDataFile<StorageEntity.Default> storageFile()

Specified by:

storageFile in interface StorageEntityCacheItem<StorageEntity.Default>

iterateReferenceIds

public final boolean iterateReferenceIds(PersistenceObjectIdAcceptor referenceIdIterator)

Specified by:

iterateReferenceIds in interface StorageEntityCacheItem<StorageEntity.Default>

exportTo

public final long exportTo(StorageLockedFile file)

Specified by:

exportTo in interface StorageEntityCacheItem<StorageEntity.Default>

copyCachedData

public final void copyCachedData(MemoryRangeReader entityDataCollector)

Specified by:

copyCachedData in interface StorageEntityCacheItem<StorageEntity.Default>

clearCache

public final long clearCache()

Specified by:

clearCache in interface StorageEntityCacheItem<StorageEntity.Default>

toString

public final String toString()

Overrides:

toString in class Object
