Constructor Detail

Default

protected Default(StorageFileManager.Default parent,
                  one.microstream.afs.types.AFile file,
                  int channelIndex,
                  long number)

Method Detail

channelIndex

public final int channelIndex()

Specified by:

channelIndex in interface StorageChannelFile

Specified by:

channelIndex in interface StorageDataFile

Specified by:

channelIndex in interface StorageHashChannelPart

number

public final long number()

Specified by:

number in interface StorageDataFile

dataLength

public long dataLength()

Specified by:

dataLength in interface StorageLiveDataFile

totalLength

public long totalLength()

Specified by:

totalLength in interface StorageLiveDataFile

executeIfUnsuedData

public boolean executeIfUnsuedData(Consumer<? super StorageLiveDataFile.Default> action)

unregisterUsageClosingData

public final boolean unregisterUsageClosingData(StorageFileUser fileUser,
                                                Consumer<? super StorageLiveDataFile.Default> closingAction)

internalOpenWriting

protected boolean internalOpenWriting()

Overrides:

internalOpenWriting in class StorageFile.Abstract

dataFillRatio

public final double dataFillRatio()

Specified by:

dataFillRatio in interface StorageLiveDataFile

hasSingleEntity

public final boolean hasSingleEntity()

Description copied from interface: StorageLiveDataFile

Querying method to check if a storage file consists of only one singular live entity. This is necessary to avoid dissolving files that are oversized because of one single oversized entity.

Specified by:

hasSingleEntity in interface StorageLiveDataFile

Returns:

true if the file contains exactly one live entity.

remove

public final void remove(StorageEntity.Default entity)

prependEntry

public final void prependEntry(StorageEntity.Default entry)

appendEntry

public final void appendEntry(StorageEntity.Default entry)

loadEntityData

public final void loadEntityData(StorageEntity.Default entity,
                                 long length,
                                 long cacheChange)

isHeadFile

public boolean isHeadFile()

Specified by:

isHeadFile in interface StorageLiveDataFile

toString

public final String toString()

Overrides:

toString in class StorageFile.Abstract
