CustomMimeTypesFileTypeDetector

All Implemented Interfaces:
```
public class CustomMimeTypesFileTypeDetector
extends FileTypeDetector
                    
```
Utility class to guess the mime-type of a file from its path or URI.
As JDK's built-in doesn't recognize all possible mime-types in particular for newer file types like YAML, or returns odd mime-types like for the TypeScript .ts extension, this class allows you to define your own extension to mime-type mapping, in addition to providing a few extra ones built-in.
When the mime-type can't be found in those mappings, or from JDK's built-in, it tries, as a fallback, to use URLConnection's capability, but it's slower as it needs to connect to the underlying URL.

 String probeContentType(Path path)
```
    Guess the mime-type of a given path.
    
    Parameters:
    
    path - the path to the file whose mime-type we want to retrieve.
    
    Returns:
    
    a string representing the mime-type of the file denoted by the path parameter, returns null if no mapping was found.
