    从接口复制的说明: RpcCallContext
    
    If the client connected and specified a codec to use, then we will use this codec making cellblocks to return. If the client did not specify a codec, we assume it does not support cellblocks and will return all content protobuf'd (though it makes our serving slower). We need to ask this question per call because a server could be hosting both clients that support cellblocks while fielding requests from clients that do not.
    
    指定者:
    
    isClientCellBlockSupported 在接口中 RpcCallContext
    
    返回:
    True if the client supports cellblocks, else return all content in pb
  - disconnectSince
```
public long disconnectSince()
```
    从接口复制的说明: RpcCallContext
    
    Check if the caller who made this IPC call has disconnected. If called from outside the context of IPC, this does nothing.
    
    指定者:
    
    disconnectSince 在接口中 RpcCallContext
    
    返回:
    < 0 if the caller is still connected. The time in ms since the disconnection otherwise
  - getResponseExceptionSize
```
public long getResponseExceptionSize()
```
    指定者:
    
    getResponseExceptionSize 在接口中 RpcCallContext
  - incrementResponseExceptionSize
```
public void incrementResponseExceptionSize(long exSize)
```
    指定者:
    
    incrementResponseExceptionSize 在接口中 RpcCallContext
  - getSize
```
public long getSize()
```
  - getResponseCellSize
```
public long getResponseCellSize()
```
    从接口复制的说明: RpcCallContext
    
    The size of response cells that have been accumulated so far. This along with the corresponding increment call is used to ensure that multi's or scans dont get too excessively large
    
    指定者:
    
    getResponseCellSize 在接口中 RpcCallContext
  - incrementResponseCellSize
```
public void incrementResponseCellSize(long cellSize)
```
    从接口复制的说明: RpcCallContext
    
    Add on the given amount to the retained cell size. This is not thread safe and not synchronized at all. If this is used by more than one thread then everything will break. Since this is called for every row synchronization would be too onerous.
    
    指定者:
    
    incrementResponseCellSize 在接口中 RpcCallContext
  - getResponseBlockSize
```
public long getResponseBlockSize()
```
    指定者:
    
    getResponseBlockSize 在接口中 RpcCallContext
  - incrementResponseBlockSize
```
public void incrementResponseBlockSize(long blockSize)
```
    指定者:
    
    incrementResponseBlockSize 在接口中 RpcCallContext
  - getDeadline
```
public long getDeadline()
```
    从接口复制的说明: RpcCallContext
    
    Return the deadline of this call. If we can not complete this call in time, we can throw a TimeoutIOException and RPCServer will drop it.
    
    指定者:
    
    getDeadline 在接口中 RpcCallContext
    
    返回:
    The system timestamp of deadline.
  - sendResponseIfReady
```
public void sendResponseIfReady()
                         throws IOException
```
    抛出:
    
    IOException
  - getRemoteUser
```
public org.apache.hadoop.security.UserGroupInformation getRemoteUser()
```
  - getRequestUser
```
public User getRequestUser()
```
    从接口复制的说明: RpcCallContext
    
    Returns the user credentials associated with the current RPC request or null if no credentials were provided.
    
    指定者:
    
    getRequestUser 在接口中 RpcCallContext
    
    返回:
    A User
  - getRequestUserName
```
public String getRequestUserName()
```
    指定者:
    
    getRequestUserName 在接口中 RpcCallContext
    
    返回:
    Current request's user name or null if none ongoing.
  - getRemoteAddress
```
public InetAddress getRemoteAddress()
```
    指定者:
    
    getRemoteAddress 在接口中 RpcCallContext
    
    返回:
    Address of remote client if a request is ongoing, else null
  - getClientVersionInfo
```
public org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.VersionInfo getClientVersionInfo()
```
    指定者:
    
    getClientVersionInfo 在接口中 RpcCallContext
    
    返回:
    the client version info, or null if the information is not present
  - isRetryImmediatelySupported
```
public boolean isRetryImmediatelySupported()
```
    指定者:
    
    isRetryImmediatelySupported 在接口中 RpcCallContext
