- com.alibaba.graphscope.communication.Communicator
- - com.alibaba.graphscope.app.GiraphComputationAdaptor<OID_T,VID_T,VDATA_T,EDATA_T>

Type Parameters:

OID_T - grape oid.

VID_T - grape vid.

VDATA_T - grape vdata.

EDATA_T - grape edata.

All Implemented Interfaces:

AppBase<OID_T,VID_T,VDATA_T,EDATA_T,GiraphComputationAdaptorContext<OID_T,VID_T,VDATA_T,EDATA_T>>, DefaultAppBase<OID_T,VID_T,VDATA_T,EDATA_T,GiraphComputationAdaptorContext<OID_T,VID_T,VDATA_T,EDATA_T>>
```
public class GiraphComputationAdaptor<OID_T,VID_T,VDATA_T,EDATA_T>
extends Communicator
implements DefaultAppBase<OID_T,VID_T,VDATA_T,EDATA_T,GiraphComputationAdaptorContext<OID_T,VID_T,VDATA_T,EDATA_T>>
```
This adaptor bridges c++ driver app and Giraph Computation.
Using raw types since we are not aware of Computation type parameters at this time.
