    Parameters:
    
    name - fully qualified class name
    
    Returns:
    
    possible signature variations for instances of the class

                            throws JiBXException
```
    Check if a value of one type can be directly assigned to another type. This is basically the equivalent of the instanceof operator, but with application to primitive types as well as object types.
    
    Parameters:
    
    from - fully qualified class name of initial type
    
    to - fully qualified class name of assignment type
    
    Returns:
