方法详细资料

getMetrics

public CircuitBreakerMetrics getMetrics()

从接口复制的说明: CircuitBreaker

Get the Circuit Breaker Metrics Object.

指定者:

getMetrics 在接口中 CircuitBreaker

allowRequest

public boolean allowRequest()

从接口复制的说明: CircuitBreaker

Every requests asks this if it is allowed to proceed or not. It is idempotent and does not modify any internal state.

指定者:

allowRequest 在接口中 CircuitBreaker

返回:

boolean whether a request should be permitted

recordAttemptSuccess

public void recordAttemptSuccess()

从接口复制的说明: CircuitBreaker

Invoked on successful executions as part of feedback mechanism when in a half-open state.

指定者:

recordAttemptSuccess 在接口中 CircuitBreaker

recordAttemptFailure

public void recordAttemptFailure()

从接口复制的说明: CircuitBreaker

Invoked on unsuccessful executions as part of feedback mechanism when in a half-open state.

指定者:

recordAttemptFailure 在接口中 CircuitBreaker

attemptExecution

public boolean attemptExecution()

从接口复制的说明: CircuitBreaker

Invoked at start of command execution to attempt an execution. This is non-idempotent - it may modify internal state.

指定者:

attemptExecution 在接口中 CircuitBreaker

close

public void close()
           throws IOException

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

抛出:

IOException
