getLocalDeletionTime

int getLocalDeletionTime()

getString

java.lang.String getString(AbstractType comparator)

validateFields

void validateFields(CFMetaData metadata)
                    throws MarshalException

Throws:

MarshalException

deepCopy

IColumn deepCopy()

clones the column, making copies of any underlying byte buffers

isLive

boolean isLive()

For a simple column, live == !isMarkedForDelete. For a supercolumn, live means it has at least one subcolumn whose timestamp is greater than the supercolumn deleted-at time.
