JSON-LD Transformers: add method to transform collections of primitive types

[paullatzelsperger]

Feature Request

It would be good to have a way to automatically transform collections of primitive types readily available.

For example, transforming a Set<String> can currently be done using the following code:

var set = jsonValue.asJsonArray().stream()
                        .map(jv -> transformString(jv, context))
                        .collect(Collectors.toSet());

That code has to be executed in every subclass. So it would be even more comfortable and less error prone if the existing transformArray method could already internally transform primitive types.

Which Areas Would Be Affected?

JSON-LD, probably the AbstractJsonLdTransformer

Why Is the Feature Desired?

Ease of use, centralizing features.

Solution Proposal

add a check to the transformArray method, if the object in question is a primitive type.
