- com.alibaba.graphscope.graph.impl.VertexDataManagerImpl<VDATA_T,GRAPE_OID_T,GRAPE_VID_T,GRAPE_VDATA_T,GRAPE_EDATA_T>

Type Parameters:

VDATA_T - giraph vertex data type

GRAPE_OID_T - grape vertex oid

GRAPE_VID_T - grape vertex vid

GRAPE_VDATA_T - grape vertex data

GRAPE_EDATA_T - grape edge data

All Implemented Interfaces:

VertexDataManager<VDATA_T>
```
public class VertexDataManagerImpl<VDATA_T extends org.apache.hadoop.io.Writable,GRAPE_OID_T,GRAPE_VID_T,GRAPE_VDATA_T,GRAPE_EDATA_T>
extends Object
implements VertexDataManager<VDATA_T>
```
Default implementation for vertex data management. Basically we retrieve all vdata from c++ fragment, and store in a java list.
