Enclosing class:

CommandLine.Model
```
public static interface CommandLine.Model.ITypeInfo
```
Encapculates type information for an option or parameter to make this information available both at runtime and at compile time (when Class values are not available). Most of the methods in this interface (but not all!) are safe to use by annotation processors.
