Example 1 with MissingTypeError

use of graphql.schema.idl.errors.MissingTypeError in project graphql-java by graphql-java.

the class SchemaTypeExtensionsChecker method checkUnionTypeExtensions.

/*
     * Union type extensions have the potential to be invalid if incorrectly defined.
     *
     * The named type must already be defined and must be a Union type.
     * The member types of a Union type extension must all be Object base types; Scalar, Interface and Union types must not be member types of a Union. Similarly, wrapping types must not be member types of a Union.
     * All member types of a Union type extension must be unique.
     * All member types of a Union type extension must not already be a member of the original Union type.
     * Any directives provided must not already apply to the original Union type.
