Adding Locale to Coercing and hence ValueResolver #2912

bbakerman · 2022-08-05T03:46:31Z

We would like to support Locale when coer-ercing values or parsing document text. So we need that passed in.

This has chosen to pass in a GraphQLContext and a Locale to a scalar Coercing so that :

a Locale can be present
the Scalar can use the context object for other purposes if it wants to

There are stacks of time where need to use ValueResolver and its methods to resolve values. We need a defaulted locale here and default GraphqlContext to make this work.

The ValueResolver has been substantially re-arranged - none of its logic has changed but the graphql context and locale have been passed on through it.

The class was 1000 lines long. Why too much code in it.

I have split it into 2 - one with the legacy value code into its own class (and then accessed via the ValueResolver) and one with code for value conversions (external to literal etc...)

But the code itself really has not changed. The tests show that - only graphql context and locale have been added

Originally I put the Parser code here (passing in Locale to it) in this PR but it was too big - this is plenty big enough already - so I will make another PR for that

Since this method doesn't carry the @NotNull return annotation anymore, should this comment be updated?

Thanks, that's a good catch. I'll fix it up
