Method Detail

markSuccess

public void markSuccess()

Description copied from interface: HystrixCircuitBreaker

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

Specified by:

markSuccess in interface HystrixCircuitBreaker

allowRequest

public boolean allowRequest()

Description copied from interface: HystrixCircuitBreaker

Every HystrixCommand requests asks this if it is allowed to proceed or not.

This takes into account the half-open logic which allows some requests through when determining if it should be closed again.

Specified by:

allowRequest in interface HystrixCircuitBreaker

Returns:

boolean whether a request should be permitted

allowSingleTest

public boolean allowSingleTest()

isOpen

public boolean isOpen()

Description copied from interface: HystrixCircuitBreaker

Whether the circuit is currently open (tripped).

Specified by:

isOpen in interface HystrixCircuitBreaker

Returns:

boolean state of circuit breaker
