Method Details

localDeletionTime

public long localDeletionTime()

Description copied from class: DeletionTime

The local server timestamp, in seconds since the unix epoch, at which this tombstone was created. This is only used for purposes of purging the tombstone after gc_grace_seconds have elapsed.

Overrides:

localDeletionTime in class DeletionTime

validate

public boolean validate()

Description copied from class: DeletionTime

Check if this deletion time is valid. This is always true, because - as we permit negative timestamps, markedForDeleteAt can be negative. - localDeletionTime is stored as an unsigned int and cannot be negative.

Overrides:

validate in class DeletionTime

Returns:

true if it is valid
