visitGraphQLAppliedDirectiveArgument

public TraversalControl visitGraphQLAppliedDirectiveArgument(GraphQLAppliedDirectiveArgument node,
                                                             TraverserContext<GraphQLSchemaElement> context)

Specified by:

visitGraphQLAppliedDirectiveArgument in interface GraphQLTypeVisitor

visitGraphQLAppliedDirective

public TraversalControl visitGraphQLAppliedDirective(GraphQLAppliedDirective node,
                                                     TraverserContext<GraphQLSchemaElement> context)

Description copied from interface: GraphQLTypeVisitor

This method will be called when a directive is applied to a schema element. The TraverserContext.getParentNode() will be the schema element that this is applied to. The graphql-java code base is trying to slowly move away from using GraphQLDirectives when they really should be GraphQLAppliedDirectives

Specified by:

visitGraphQLAppliedDirective in interface GraphQLTypeVisitor

Parameters:

node - the applied directive

context - the traversal context

Returns:

how to control the visitation processing

visitGraphQLArgument

visitGraphQLDirective

public TraversalControl visitGraphQLDirective(GraphQLDirective node,
                                              TraverserContext<GraphQLSchemaElement> context)

Description copied from interface: GraphQLTypeVisitor

This method will be called twice. Once for a directive definition in a schema and then do each time a directive is applied to a schema element When it's applied to a schema element then TraverserContext.getParentNode() will be the schema element that this is applied to. The graphql-java code base is trying to slowly move away from using GraphQLDirectives when they really should be GraphQLAppliedDirectives and this is another place that has been left in. In the future this behavior will change and this will only visit directive definitions of a schema, not where they are applied.

Specified by:

visitGraphQLDirective in interface GraphQLTypeVisitor

Parameters:

node - the directive

context - the traversal context

Returns:

how to control the visitation processing
