类 DelegatingHBaseRpcController

java.lang.Object

org.apache.hadoop.hbase.ipc.DelegatingHBaseRpcController

所有已实现的接口:

CellScannable, HBaseRpcController, org.apache.hbase.thirdparty.com.google.protobuf.RpcController

@InterfaceAudience.Private
public class DelegatingHBaseRpcController
extends Object
implements HBaseRpcController

Simple delegating controller for use with the RpcControllerFactory to help override standard behavior of a HBaseRpcController. Used testing.

DelegatingHBaseRpcController

public DelegatingHBaseRpcController(HBaseRpcController delegate)

方法详细资料

reset

public void reset()

指定者:

reset 在接口中 org.apache.hbase.thirdparty.com.google.protobuf.RpcController

failed

public boolean failed()

指定者:

failed 在接口中 org.apache.hbase.thirdparty.com.google.protobuf.RpcController

errorText

public String errorText()

指定者:

errorText 在接口中 org.apache.hbase.thirdparty.com.google.protobuf.RpcController

startCancel

public void startCancel()

指定者:

startCancel 在接口中 org.apache.hbase.thirdparty.com.google.protobuf.RpcController

setFailed

public void setFailed(String reason)

指定者:

setFailed 在接口中 org.apache.hbase.thirdparty.com.google.protobuf.RpcController

isCanceled

public boolean isCanceled()

指定者:

isCanceled 在接口中 org.apache.hbase.thirdparty.com.google.protobuf.RpcController

notifyOnCancel

public void notifyOnCancel(org.apache.hbase.thirdparty.com.google.protobuf.RpcCallback<Object> callback)

从接口复制的说明: HBaseRpcController

A little different from the basic RpcController:

1. You can register multiple callbacks to an HBaseRpcController.
2. The callback will not be called if the rpc call is finished without any cancellation.
3. You can call me at client side also.

指定者:

notifyOnCancel 在接口中 HBaseRpcController

指定者:

notifyOnCancel 在接口中 org.apache.hbase.thirdparty.com.google.protobuf.RpcController

cellScanner

public CellScanner cellScanner()

指定者:

cellScanner 在接口中 CellScannable

setCellScanner

public void setCellScanner(CellScanner cellScanner)

从接口复制的说明: HBaseRpcController

Only used to send cells to rpc server, the returned cells should be set by HBaseRpcController.setDone(CellScanner).

指定者:

setCellScanner 在接口中 HBaseRpcController

setPriority

public void setPriority(int priority)

指定者:

setPriority 在接口中 HBaseRpcController

参数:

priority - Priority for this request; should fall roughly in the range HConstants.NORMAL_QOS to HConstants.HIGH_QOS

setPriority

public void setPriority(TableName tn)

指定者:

setPriority 在接口中 HBaseRpcController

参数:

tn - Set priority based off the table we are going against.

getPriority

public int getPriority()

指定者:

getPriority 在接口中 HBaseRpcController

返回:

The priority of this request

getCallTimeout

public int getCallTimeout()

指定者:

getCallTimeout 在接口中 HBaseRpcController

setCallTimeout

public void setCallTimeout(int callTimeout)

指定者:

setCallTimeout 在接口中 HBaseRpcController

hasCallTimeout

public boolean hasCallTimeout()

指定者:

hasCallTimeout 在接口中 HBaseRpcController

setFailed

public void setFailed(IOException e)

从接口复制的说明: HBaseRpcController

Set failed with an exception to pass on. For use in async rpc clients

指定者:

setFailed 在接口中 HBaseRpcController

参数:

e - exception to set with

getFailed

public IOException getFailed()

从接口复制的说明: HBaseRpcController

Return the failed exception, null if not failed.

指定者:

getFailed 在接口中 HBaseRpcController

setDone

public void setDone(CellScanner cellScanner)

从接口复制的说明: HBaseRpcController

IMPORTANT: always call this method if the call finished without any exception to tell the HBaseRpcController that we are done.

指定者:

setDone 在接口中 HBaseRpcController

notifyOnCancel

public void notifyOnCancel(org.apache.hbase.thirdparty.com.google.protobuf.RpcCallback<Object> callback,
                           HBaseRpcController.CancellationCallback action)
                    throws IOException

从接口复制的说明: HBaseRpcController

If not cancelled, add the callback to cancellation callback list. And then execute the action with the cancellation state as a parameter. The implementation should guarantee that the cancellation state does not change during this call.

指定者:

notifyOnCancel 在接口中 HBaseRpcController

抛出:

IOException
