- com.carrotsearch.randomizedtesting.rules.TestRuleAdapter
- - org.apache.lucene.util.TestRuleRestoreSystemProperties

All Implemented Interfaces:

org.junit.rules.TestRule
```
public class TestRuleRestoreSystemProperties
extends com.carrotsearch.randomizedtesting.rules.TestRuleAdapter
```
Restore a given set of system properties to a snapshot taken at the beginning of the rule.
This is semantically similar to SystemPropertiesRestoreRule but the list of properties to restore must be provided explicitly (because the security manager prevents us from accessing the whole set of properties).
All properties to be restored must have r/w property permission.
