Method Detail

toStringList

@NotNull
public static Optional<List<String>> toStringList(@Nullable
                                                            List<?> value)

Constructs a list of strings from the given list of unknown type. The returned optional is never empty, unless the given value is null.

The individual elements of the list are processed each one by one. If there is an element incompatible, it is skipped and will not appear in the returned list. Please learn more about compatible types at the main content method Section.getOptionalString(Route).

Parameters:

value - the list to construct

Returns:

list of strings

toIntList

@NotNull
public static Optional<List<Integer>> toIntList(@Nullable
                                                          List<?> value)

Constructs a list of integers from the given list of unknown type. The returned optional is never empty, unless the given value is null.
