Class GraphQLSchemaParser

  • All Implemented Interfaces:
    
public class GraphQLSchemaParser

    Parses GraphQL schema files and extracts type definitions using ViaductSchema types. This follows the same approach as the Kotlin codegen, using ViaductSchema as the abstraction layer instead of graphql-java types directly.

        packageName - the package name for generated enums
        Returns:

        the list of enum models

      • extractObjects

         List<ObjectModel> extractObjects(ViaductSchema schema, String packageName)

        Extracts object models from a ViaductSchema. Excludes root types (Query, Mutation, Subscription).

        Parameters:
        schema - the ViaductSchema
        packageName - the package name for generated objects
        Returns:

        Parameters:
        schema - the ViaductSchema
        packageName - the package name for generated objects
        includeRootTypes - if true, includes Query, Mutation, Subscription types
