Method Detail

set

public void set(org.apache.flink.core.memory.MemorySegment bucket,
                org.apache.flink.core.memory.MemorySegment[] overflowSegments,
                BinaryHashPartition partition,

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<org.apache.flink.table.data.binary.BinaryRowData>

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:

getRow in interface RowIterator<org.apache.flink.table.data.binary.BinaryRowData>
