- - com.alibaba.graphscope.context.GiraphComputationAdaptorContext<OID_T,VID_T,VDATA_T,EDATA_T>

Type Parameters:

OID_T -

VID_T -

VDATA_T -

EDATA_T -

All Implemented Interfaces:

ContextBase, DefaultContextBase<OID_T,VID_T,VDATA_T,EDATA_T>
```
public class GiraphComputationAdaptorContext<OID_T,VID_T,VDATA_T,EDATA_T>
extends VertexDataContext<IFragment<OID_T,VID_T,VDATA_T,EDATA_T>,VDATA_T>
implements DefaultContextBase<OID_T,VID_T,VDATA_T,EDATA_T>
```
Generic adaptor context class. The type parameter OID,VID_VDATA_T,EDATA_T is irrelevant to User writables. They are type parameters for grape fragment. We need them to support multiple set of actual type parameters in one adaptor.

    CAUTION: THIS METHOD SHALL BE CALLED in JNI after initCommunicator..
    With communicatorAddress passed, we init a FFICommunicator obj with that address.
    
    Specified by:
    
    Init in interface DefaultContextBase<OID_T,VID_T,VDATA_T,EDATA_T>
    
    Parameters:
    
    frag - The graph fragment providing accesses to graph data.
    
    messageManager - The message manger which manages messages between fragments.
    
    jsonObject - String args from cmdline.
    
    See Also:
    
    IFragment, DefaultMessageManager, JSONObject

    For giraph applications, we need to run postApplication method after all computation.
    
    Specified by:
    
    Output in interface DefaultContextBase<OID_T,VID_T,VDATA_T,EDATA_T>
    
    Parameters:
    
    frag - The graph fragment contains the graph info.
