Method Detail

advanceNext

public boolean advanceNext()

Description copied from interface: 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().

Specified by:

advanceNext in interface RowIterator<T extends org.apache.flink.table.data.RowData>

getRow

public T getRow()

Description copied from interface: RowIterator

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

Specified by:

getRow in interface RowIterator<T extends org.apache.flink.table.data.RowData>
