DelegatingHBaseRpcController (Apache HBase

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.

所有方法实例方法具体方法
限定符和类型	方法和说明
`CellScanner`	`cellScanner()`
`String`	`errorText()`
`boolean`	`failed()`
`int`	`getCallTimeout()`
`IOException`	`getFailed()` Return the failed exception, null if not failed.
`int`	`getPriority()`
`boolean`	`hasCallTimeout()`
`boolean`	`isCanceled()`
`void`	`notifyOnCancel(org.apache.hbase.thirdparty.com.google.protobuf.RpcCallback<Object> callback)` A little different from the basic RpcController: You can register multiple callbacks to an `HBaseRpcController`.
`void`	`notifyOnCancel(org.apache.hbase.thirdparty.com.google.protobuf.RpcCallback<Object> callback, HBaseRpcController.CancellationCallback action)` If not cancelled, add the callback to cancellation callback list.
`void`	`reset()`
`void`	`setCallTimeout(int callTimeout)`
`void`	`setCellScanner(CellScanner cellScanner)` Only used to send cells to rpc server, the returned cells should be set by `HBaseRpcController.setDone(CellScanner)`.
`void`	`setDone(CellScanner cellScanner)` IMPORTANT: always call this method if the call finished without any exception to tell the `HBaseRpcController` that we are done.
`void`	`setFailed(IOException e)` Set failed with an exception to pass on.
`void`	`setFailed(String reason)`
`void`	`setPriority(int priority)`

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.

    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:

```
    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)

```
    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

```
    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:
