public abstract class BaseRowProcessorEndpoint<S extends com.google.protobuf.Message,T extends com.google.protobuf.Message>
extends org.apache.hadoop.hbase.protobuf.generated.RowProcessorProtos.RowProcessorService
implements RegionCoprocessor

This class demonstrates how to implement atomic read-modify-writes using Region.processRowsWithLocks(org.apache.hadoop.hbase.regionserver.RowProcessor<?, ?>) and Coprocessor endpoints.

process

public void process(com.google.protobuf.RpcController controller,
                    org.apache.hadoop.hbase.protobuf.generated.RowProcessorProtos.ProcessRequest request,
                    com.google.protobuf.RpcCallback<org.apache.hadoop.hbase.protobuf.generated.RowProcessorProtos.ProcessResponse> done)

Pass a processor to region to process multiple rows atomically. The RowProcessor implementations should be the inner classes of your RowProcessorEndpoint. This way the RowProcessor can be class-loaded with the Coprocessor endpoint together. See TestRowProcessorEndpoint for example. The request contains information for constructing processor (see constructRowProcessorFromRequest(org.apache.hadoop.hbase.protobuf.generated.RowProcessorProtos.ProcessRequest). The processor object defines the read-modify-write procedure.

指定者:

process 在类中 org.apache.hadoop.hbase.protobuf.generated.RowProcessorProtos.RowProcessorService

getServices

public Iterable<com.google.protobuf.Service> getServices()

指定者:

getServices 在接口中 Coprocessor

start

public void start(CoprocessorEnvironment env)
           throws IOException

Stores a reference to the coprocessor environment provided by the RegionCoprocessorHost from the region where this coprocessor is loaded. Since this is a coprocessor endpoint, it always expects to be loaded on a table region, so always expects this to be an instance of RegionCoprocessorEnvironment.

指定者:

start 在接口中 Coprocessor

参数:

env - the environment provided by the coprocessor host

抛出:

IOException - if the provided environment is not an instance of RegionCoprocessorEnvironment

stop

public void stop(CoprocessorEnvironment env)
          throws IOException

指定者:

stop 在接口中 Coprocessor

抛出:

IOException
