GQLNode

interface GQLNode

A node in the GraphQL AST.

The structure of the different nodes matches closely the one of the GraphQL specification (https://spec.graphql.org/June2018/#sec-Appendix-Grammar-Summary.Document)

Compared to the Antlr com.apollographql.apollo3.generated.antlr.GraphQLParser.DocumentContext, a GQLDocument is a lot simpler and allows for easy modifying a document (using GQLNode.transform) and outputing them to a okio.BufferedSink.

Whitespace tokens are not mapped to GQLNodes so some formatting will be lost during modification
