类 RpcRetryingCallerImpl<T>

java.lang.Object

org.apache.hadoop.hbase.client.RpcRetryingCallerImpl<T>

所有已实现的接口:

RpcRetryingCaller<T>

@InterfaceAudience.Private
public class RpcRetryingCallerImpl<T>
extends Object
implements RpcRetryingCaller<T>

Runs an rpc'ing RetryingCallable. Sets into rpc client threadlocal outstanding timeouts as so we don't persist too much. Dynamic rather than static so can set the generic appropriately. This object has a state. It should not be used by in parallel by different threads. Reusing it is possible however, even between multiple threads. However, the user will have to manage the synchronization on its side: there is no synchronization inside the class.

方法详细资料

cancel

public void cancel()

指定者:

cancel 在接口中 RpcRetryingCaller<T>

callWithRetries

public T callWithRetries(RetryingCallable<T> callable,
                         int callTimeout)
                  throws IOException,
                         RuntimeException

从接口复制的说明: RpcRetryingCaller

Retries if invocation fails.

指定者:

callWithRetries 在接口中 RpcRetryingCaller<T>

参数:

callable - The RetryingCallable to run.

callTimeout - Timeout for this call

返回:

an object of type T

抛出:

IOException - if a remote or network exception occurs

RuntimeException - other unspecified error

callWithoutRetries

public T callWithoutRetries(RetryingCallable<T> callable,
                            int callTimeout)
                     throws IOException,
                            RuntimeException

从接口复制的说明: RpcRetryingCaller

Call the server once only. RetryingCallable has a strange shape so we can do retries. Use this invocation if you want to do a single call only (A call to RetryingCallable.call(int) will not likely succeed).

指定者:

callWithoutRetries 在接口中 RpcRetryingCaller<T>

返回:

an object of type T

抛出:

IOException - if a remote or network exception occurs

RuntimeException - other unspecified error

toString

public String toString()

覆盖:

toString 在类中 Object
