Method Detail

dataLength

public final long dataLength()

Specified by:

dataLength in interface StorageEntity

Returns:

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

typeId

public long typeId()

Specified by:

typeId in interface StorageEntity

Returns:

The entity's type id.

storagePosition

public final long storagePosition()

Specified by:

storagePosition in interface StorageEntity

cachedDataLength

public final long cachedDataLength()

Description copied from interface: StorageEntity

The length this entity occupies in the cache. This might 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

Returns:

The length this entity occupies in the cache.

hasReferences

public final boolean hasReferences()

Specified by:

hasReferences in interface StorageEntity

Returns:

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

objectId

public final long objectId()

Specified by:

objectId in interface StorageEntity

Returns:

The entity's biunique identifying id number.

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

Returns:

approximate system time that this particular entity has been last touched

storageFile

public final StorageLiveDataFile storageFile()

Specified by:

storageFile in interface StorageEntity

iterateReferenceIds

public final boolean iterateReferenceIds(one.microstream.persistence.types.PersistenceObjectIdAcceptor referenceIdIterator)

Specified by:

iterateReferenceIds in interface StorageEntity

exportTo

public final long exportTo(one.microstream.afs.types.AWritableFile file)

Specified by:

exportTo in interface StorageEntity

copyCachedData

public final void copyCachedData(MemoryRangeReader entityDataCollector)

Specified by:

copyCachedData in interface StorageEntity

clearCache

public final long clearCache()

Specified by:

clearCache in interface StorageEntity

toString

public final String toString()

Overrides:

toString in class Object
