BackoffStrategy (Camunda Platform Javadocs 7.20.0-SNAPSHOT)

All Known Subinterfaces:

ErrorAwareBackoffStrategy

All Known Implementing Classes:

ExponentialBackoffStrategy, ExponentialErrorBackoffStrategy
```
public interface BackoffStrategy
```
Provides a way to define a back off between fetch and lock requests.
Note: Since an implementation of this interface may be executed by multiple threads, it is recommended to implement the custom backoff strategy in a thread-safe manner.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`long`	`calculateBackoffTime()`	Calculates the back off time and is invoked after `reconfigure(List)`.
`void`	`reconfigure(List<ExternalTask> externalTasks)`	Reconfigures the back off strategy based on the fetched external tasks and is invoked before `calculateBackoffTime()`.

- Method Detail
  - reconfigure
```
void reconfigure(List<ExternalTask> externalTasks)
```
    Reconfigures the back off strategy based on the fetched external tasks and is invoked before calculateBackoffTime().
    The implementation might count the amount of invocations and realize a strategy reset.
    
    Parameters:
    
    externalTasks - which have been fetched
  - calculateBackoffTime
```
long calculateBackoffTime()
```
    Calculates the back off time and is invoked after reconfigure(List).
    
    Returns:
    
    the back off time between fetch and lock requests in milliseconds
