Method Details

findNonNullFields

public static List<Field> findNonNullFields(@NonNull
 @NonNull Class<?> _class)

The method uses reflection to find all declared fields of a class that have been marked (via commonly used annotations) as being Non-Null. This method will also look at the class's package level to see if the API for that package is defaulted as Non-Null. ANY annotation that has runtime retention and matches on of the simple annotation names (minus any package) will be considered a match.

Parameters:

_class - The class to reflect over

Returns:

A list of fields marked as non-null, sorted by their name in alphabetical order.
