- org.apache.thrift.partial.Validate

```
public final class Validate
extends java.lang.Object
```
A superset of Validate class in Apache commons lang3. It provides consistent message strings for frequently encountered checks. That simplifies callers because they have to supply only the name of the argument that failed a check instead of having to supply the entire message.
