Method Detail

getKeyspace

public java.lang.String getKeyspace()

Specified by:

getKeyspace in interface IReadCommand

createMessage

public abstract MessageOut<? extends AbstractRangeCommand> createMessage()

forSubRange

public abstract AbstractRangeCommand forSubRange(AbstractBounds<RowPosition> range)

withUpdatedLimit

public abstract AbstractRangeCommand withUpdatedLimit(int newLimit)

limit

public abstract int limit()

countCQL3Rows

public abstract boolean countCQL3Rows()

ignoredTombstonedPartitions

public boolean ignoredTombstonedPartitions()

Returns true if tombstoned partitions should not be included in results or count towards the limit. See CASSANDRA-8490 for more details on why this is needed (and done this way).

getTimeout

public long getTimeout()

Specified by:

getTimeout in interface IReadCommand
