Optional Element Summary

Optional Elements
Modifier and Type	Optional Element and Description
`long`	`delay` The delay.
`java.time.temporal.ChronoUnit`	`delayUnit`
`java.lang.Class<? extends java.lang.Throwable>[]`	`failOn` Define the failure criteria
`double`	`failureRatio` The failure threshold to trigger the circuit to open.
`int`	`requestVolumeThreshold` The number of consecutive requests in a rolling window that will trip the circuit.
`int`	`successThreshold` For an open circuit, after the delay period is reached, once the successThreshold is reached, the circuit is back to close again.

  - failOn
```
public abstract java.lang.Class<? extends java.lang.Throwable>[] failOn
```
    Define the failure criteria
    
    Returns:
    
    the failure exception
    
    Default:
    
    java.lang.Throwable.class
- - delay
```
public abstract long delay
```
    The delay. The value must be greater than or equal to 0. 0 means no delay.
    
    Returns:
    
    The delay time after the circuit is open
    
    Default:
    
    5000L
- - delayUnit
```
public abstract java.time.temporal.ChronoUnit delayUnit
```
    Returns:
    
    The delay unit after the circuit is open
    
    Default:
    
    java.time.temporal.ChronoUnit.MILLIS
- - requestVolumeThreshold
```
public abstract int requestVolumeThreshold
```
    The number of consecutive requests in a rolling window that will trip the circuit. The value must be greater than or equal to 1.
    
    Returns:
    
    the number of the consecutive requests in a rolling window
    
    Default:
    
    20
- - failureRatio
```
public abstract double failureRatio
```
    The failure threshold to trigger the circuit to open. e.g. if the requestVolumeThreshold is 20 and failureRation is .50, more than 10 failures in 20 consecutive requests will trigger the circuit to open. The value must be between 0 and 1 inclusive.
    
    Returns:
    
    The failure threshold to open the circuit
    
    Default:
    
    0.5
- - successThreshold
```
public abstract int successThreshold
```
    For an open circuit, after the delay period is reached, once the successThreshold is reached, the circuit is back to close again. The value must be greater than or equal to 1.
    
    Returns:
    
    The success threshold to fully close the circuit
    
    Default:
    
    1
