All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`void`	`onCallBreakerOpenFailure()` Invoked for each call when the future is completed with `akka.pattern.CircuitBreakerOpenException`
`void`	`onCallFailure(long elapsedNanos)` Invoked for each call when the future is completed with exception, except for `TimeoutException` and `CircuitBreakerOpenException` that are handled by separate methods.
`void`	`onCallSuccess(long elapsedNanos)` Invoked for each successful call.
`void`	`onCallTimeoutFailure(long elapsedNanos)` Invoked for each call when the future is completed with `java.util.concurrent.TimeoutException`
`void`	`onClose()` Invoked when the circuit breaker transitions to the close state.
`void`	`onHalfOpen()` Invoked when the circuit breaker transitions to the half-open state after reset timeout.
`void`	`onOpen()` Invoked when the circuit breaker transitions to the open state.
`void`	`stop()` Called when the circuit breaker is removed, e.g.

- Method Detail
  - onOpen
```
void onOpen()
```
    Invoked when the circuit breaker transitions to the open state.
  - onClose
```
void onClose()
```
    Invoked when the circuit breaker transitions to the close state.
  - onHalfOpen
```
void onHalfOpen()
```
    Invoked when the circuit breaker transitions to the half-open state after reset timeout.
  - onCallSuccess
```
void onCallSuccess(long elapsedNanos)
```
    Invoked for each successful call.
    
    Parameters:
    
    elapsedNanos - the elapsed duration of the call in nanoseconds
  - onCallFailure
```
void onCallFailure(long elapsedNanos)
```
    Invoked for each call when the future is completed with exception, except for `TimeoutException` and `CircuitBreakerOpenException` that are handled by separate methods.
    
    Parameters:
    
    elapsedNanos - the elapsed duration of the call in nanoseconds
  - onCallTimeoutFailure
```
void onCallTimeoutFailure(long elapsedNanos)
```
    Invoked for each call when the future is completed with `java.util.concurrent.TimeoutException`
    
    Parameters:
    
    elapsedNanos - the elapsed duration of the call in nanoseconds
  - onCallBreakerOpenFailure
```
void onCallBreakerOpenFailure()
```
    Invoked for each call when the future is completed with `akka.pattern.CircuitBreakerOpenException`
  - stop
```
void stop()
```
    Called when the circuit breaker is removed, e.g. expired due to inactivity. It is also called if the circuit breaker is re-configured, before calling CircuitBreakerMetricsProvider.start(java.lang.String).
