updateChecksum

public void updateChecksum()

Description copied from interface: ChecksumEntry

Re-computes and stores checksum for the entry. This method shouldn't be called before or after ordinary operations like MapAbsentEntry.doInsert(Data), MapEntry.doReplaceValue(Data): it is performed automatically underneath. Call this method, only when value bytes was updated directly, for example though flyweight implementation of a value interface.

Specified by:

updateChecksum in interface ChecksumEntry

checkSum

public boolean checkSum()

Description copied from interface: ChecksumEntry

Computes checksum from the entry bytes and checks whether it is equal to the stored checksum.

Specified by:

checkSum in interface ChecksumEntry

Returns:

true if stored checksum equals to checksum computed from the entry bytes

key

@NotNull
public Data<K> key()

Description copied from interface: HashEntry

Returns the entry key.

Specified by:

key in interface HashEntry<K>

initEntrySizeInChunks

public void initEntrySizeInChunks(int actuallyUsedChunks)

innerRemoveEntryExceptHashLookupUpdate

public void innerRemoveEntryExceptHashLookupUpdate()
