Example 11 with Directive

use of graphql.language.Directive in project graphql-java by graphql-java.

the class SchemaTypeExtensionsChecker method checkObjectTypeExtensions.

/*
     * Object type extensions have the potential to be invalid if incorrectly defined.

     * The named type must already be defined and must be an Object type.
     * The fields of an Object type extension must have unique names; no two fields may share the same name.
     * Any fields of an Object type extension must not be already defined on the original Object type.
     * Any directives provided must not already apply to the original Object type.
     * Any interfaces provided must not be already implemented by the original Object type.
     * The resulting extended object type must be a super-set of all interfaces it implements.
