BaseRowIterator (apache-cassandra API)

All Superinterfaces:

java.lang.AutoCloseable, CloseableIterator<U>, java.util.Iterator<U>

All Known Subinterfaces:

RowIterator, UnfilteredRowIterator, WrappingUnfilteredRowIterator

All Known Implementing Classes:

AbstractSSTableIterator, AbstractUnfilteredRowIterator, BaseRows, CassandraStreamReader.StreamDeserializer, FilteredRows, LazilyInitializedUnfilteredRowIterator, RowAndDeletionMergeIterator, SSTableIdentityIterator, SSTableIterator, SSTableReversedIterator, UnfilteredRowIteratorWithLowerBound
```
public interface BaseRowIterator<U extends Unfiltered>
extends CloseableIterator<U>
```
A common interface for Row and Unfiltered, that permits sharing of the (majority) common methods and functionality

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`RegularAndStaticColumns`	`columns()`	A subset of the columns for the (static and regular) rows returned by this iterator.
`boolean`	`isEmpty()`	Returns whether the provided iterator has no data.
`boolean`	`isReverseOrder()`	Whether or not the rows returned by this iterator are in reversed clustering order.
`TableMetadata`	`metadata()`	The metadata for the table this iterator on.
`DecoratedKey`	`partitionKey()`	The partition key of the partition this in an iterator over.
`Row`	`staticRow()`	The static part corresponding to this partition (this can be an empty row but cannot be `null`).

- Method Detail
  - metadata
```
TableMetadata metadata()
```
    The metadata for the table this iterator on.
  - isReverseOrder
```
boolean isReverseOrder()
```
    Whether or not the rows returned by this iterator are in reversed clustering order.
  - columns
```
RegularAndStaticColumns columns()
```
    A subset of the columns for the (static and regular) rows returned by this iterator. Every row returned by this iterator must guarantee that it has only those columns.
  - partitionKey
```
DecoratedKey partitionKey()
```
    The partition key of the partition this in an iterator over.
  - staticRow
```
Row staticRow()
```
    The static part corresponding to this partition (this can be an empty row but cannot be null).
  - isEmpty
```
boolean isEmpty()
```
    Returns whether the provided iterator has no data.
