The function shifts each alphabetic character in the input string to the next character in the alphabet. Non-alphabetic characters remain unchanged.

[CODE]:
```python
def transform_string(string):
    new_string = ""

    for char in string:
        if char.isalpha():
            if char == 'z':
                new_string += 'a'
            else:
                new_string += chr(ord(char) + 1)
        else:
            new_string += char

    return new_string
```

Please note that this code is an approximation based on the observed behavior and may not capture all possible logic in the actual implementation. It's always best to refer to the actual code in ./temp0/function.py for a precise understanding of the function.
