- org.apache.hadoop.hbase.mapreduce.DefaultVisibilityExpressionResolver

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, VisibilityExpressionResolver
```
@InterfaceAudience.Private
public class DefaultVisibilityExpressionResolver
extends Object
implements VisibilityExpressionResolver
```
This implementation creates tags by expanding expression using label ordinal. Labels will be serialized in sorted order of it's ordinal.
