| Modifier and Type | Class and Description | 
|---|---|
| protected static class  | AbstractCircuitBreaker.StateAn internal enumeration representing the different states of a circuit
 breaker. | 
| Modifier and Type | Field and Description | 
|---|---|
| static String | PROPERTY_NAMEThe name of the open property as it is passed to registered

| AbstractCircuitBreaker()Creates an  AbstractCircuitBreaker. | 
| Modifier and Type | Method and Description | 
|---|---|
| void | addChangeListener(PropertyChangeListener listener)Adds a change listener to this circuit breaker. | 
| protected void | changeState(AbstractCircuitBreaker.State newState)Changes the internal state of this circuit breaker. | 
| abstract boolean | checkState()Checks the state of this circuit breaker and changes it if necessary. | 
| void | close()Closes this circuit breaker. | 
| abstract boolean | incrementAndCheckState(T increment)Increments the monitored value and performs a check of the current state of this
 circuit breaker. | 
| boolean | isClosed()Returns the current closed state of this circuit breaker. | 
| boolean | isOpen()Returns the current open state of this circuit breaker. | 
| protected static boolean | isOpen(AbstractCircuitBreaker.State state)Converts the given state value to a boolean open property. | 
| void | open()Opens this circuit breaker. | 
| void | removeChangeListener(PropertyChangeListener listener)Removes the specified change listener from this circuit breaker. |
