createBuffer

public static BinaryKVInMemorySortBuffer createBuffer(NormalizedKeyComputer normalizedKeyComputer,
                                                      BinaryRowSerializer keySerializer,
                                                      BinaryRowSerializer valueSerializer,
                                                      RecordComparator comparator,
                                                      ArrayList<org.apache.flink.core.memory.MemorySegment> recordBufferSegments,
                                                      long numElements,
                                                      MemorySegmentPool pool)
                                               throws IOException

抛出:

IOException

writeToOutput

public void writeToOutput(org.apache.flink.runtime.memory.AbstractPagedOutputView output)
                   throws IOException

从类复制的说明: BinaryIndexedSortable

Spill: Write all records to a AbstractPagedOutputView.

覆盖:

writeToOutput 在类中 BinaryIndexedSortable

抛出:

IOException

getIterator

public final org.apache.flink.util.MutableObjectIterator<org.apache.flink.api.java.tuple.Tuple2<BinaryRow,BinaryRow>> getIterator()

Gets an iterator over all KV records in this buffer in their logical order.

返回:

An iterator returning the records in their logical order.
