WrappedRowIterator

public WrappedRowIterator(org.apache.flink.util.MutableObjectIterator<T> iterator,
                          T reuse)

方法详细资料

advanceNext

public boolean advanceNext()

从接口复制的说明: RowIterator

Advance this iterator by a single row. Returns `false` if this iterator has no more rows and `true` otherwise. If this returns `true`, then the new row can be retrieved by calling RowIterator.getRow().

指定者:

advanceNext 在接口中 RowIterator<T extends org.apache.flink.table.data.RowData>

getRow

public T getRow()

从接口复制的说明: RowIterator

Retrieve the row from this iterator. This method is idempotent. It is illegal to call this method after [[advanceNext()]] has returned `false`.

指定者:

getRow 在接口中 RowIterator<T extends org.apache.flink.table.data.RowData>
