- Method Detail
  - sources
```
default void sources(int sources)
```
    Number of path to generate entries iterator in flush method. This method must be called before flush if sort with subKv.
  - combiner
```
default org.apache.hugegraph.computer.core.combiner.Combiner<Pointer> combiner()
```
    Combiner entries with the same key.
  - flush
```
void flush(EntryIterator entries,
           KvEntryFileWriter writer)
    throws java.io.IOException
```
    Combine the list of inputValues, and write the inputKey and combined result length and results to HgkvDirWriter. The caller maybe needs to call the sources method before call this method.
