Policy (KIE :: Execution Server :: Services :: Common 7.61.0.Final API)

All Known Implementing Classes:

KeepLatestContainerOnlyPolicy
```
public interface Policy
```
Policy that can be applied on KIE Server components on regular basis. It can be to perform cleanup operation (like disposing old containers) it can be time based restriction in using containers and more.

```
void apply(KieServerRegistry kieServerRegistry,
           KieServer kieServer)
```
    Applies given policy on kie server. Actual operations depends on implementation though they can do any operation based on given parameters. kieServer should be used to alter state of the kie server while kieServerRegistry should be used to locate information to evaluate if policy can be applied
    
    Parameters:
    
    kieServerRegistry - registry of the kie server
    
    kieServer - actual instance representing kie server to perform operations on containers
