HalfOpenState

public HalfOpenState(CircuitBreakerImpl<R> breaker)

Method Details

tryAcquirePermit

public boolean tryAcquirePermit()

Specified by:

tryAcquirePermit in class CircuitState<R>

releasePermit

public void releasePermit()

Overrides:

releasePermit in class CircuitState<R>

getState

public CircuitBreaker.State getState()

Specified by:

getState in class CircuitState<R>

handleConfigChange

public void handleConfigChange()

Overrides:

handleConfigChange in class CircuitState<R>

checkThreshold

void checkThreshold(ExecutionContext<R> context)

Checks to determine if a threshold has been met and the circuit should be opened or closed.

If a success threshold is configured, the circuit is opened or closed based on whether the ratio was exceeded.

Else the circuit is opened or closed based on whether the failure threshold was exceeded.

Overrides:

checkThreshold in class CircuitState<R>

capacityFor

private static int capacityFor(CircuitBreaker<?> breaker)

Returns the capacity of the breaker in the half-open state.
