  - init
```
default void init(java.util.Properties securityProps)
```
    Given the security props of the server, properly initialize the post processor for the server. Initialized at cache creation

    securityProps - security properties
  - processRegionValue
```
java.lang.Object processRegionValue(java.lang.Object principal,
                                    java.lang.String regionName,
