    Description copied from interface: ArgumentCount
    
    Enables custom validation of argument counts after ArgumentCount.getMinCount() and ArgumentCount.getMaxCount() have been validated.
    
    Specified by:
    
    isValidCount in interface ArgumentCount
    
    Parameters:
    
    count - total number of arguments including each argument for a vararg function call
  - getMinCount
```
public Optional<Integer> getMinCount()
