Method Details

advanceNext

public boolean advanceNext()

getRow

public org.apache.flink.table.data.binary.BinaryRowData 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:
