Method Detail

delete

public void delete(AbstractColumnContainer cc2)

delete

public void delete(DeletionInfo delInfo)

setDeletionInfo

public void setDeletionInfo(DeletionInfo delInfo)

isMarkedForDelete

public boolean isMarkedForDelete()

Specified by:

isMarkedForDelete in interface IColumnContainer

deletionInfo

public DeletionInfo deletionInfo()

Specified by:

deletionInfo in interface IColumnContainer

getComparator

public AbstractType<?> getComparator()

Specified by:

getComparator in interface IColumnContainer

Specified by:

getComparator in interface IIterableColumns

maybeResetDeletionTimes

public void maybeResetDeletionTimes(int gcBefore)

Drops expired row-level tombstones. Normally, these are dropped once the row no longer exists, but if new columns are inserted into the row post-deletion, they can keep the row tombstone alive indefinitely, with non-intuitive results. See https://issues.apache.org/jira/browse/CASSANDRA-2317

replace

public boolean replace(IColumn oldColumn,
                       IColumn newColumn)

Description copied from interface: IColumnContainer

Replace oldColumn if represent by newColumn. Returns true if oldColumn was present (and thus replaced) oldColumn and newColumn should have the same name. !NOTE! This should only be used if you know this is what you need. To add a column such that it use the usual column resolution rules in a thread safe manner, use addColumn.
