public interface ChecksumEntry

Abstracts entries of hash containers, created by ChronicleHashBuilders with ChronicleHashBuilder.checksumEntries(boolean) configured to true.

Method Summary

Modifier and Type	Method and Description
boolean	checkSum() Computes checksum from the entry bytes and checks whether it is equal to the stored checksum.
void	updateChecksum() Re-computes and stores checksum for the entry.

Method Detail

updateChecksum

void updateChecksum()

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 Chronicle-Value-generated interface.

checkSum

boolean checkSum()

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

Returns:

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