Example 1 with DefaultEdge

use of graphql.relay.DefaultEdge in project synapse by americanexpress.

the class ConnectionUtil method create.

/**
 * Create the {@link Connection}.
 * @param <T> type of {@link UniversallyUniqueIdentifiable} element
 * @param elements used to create the edges of the connection
 * @param first number of elements
 * @param after the opaque cursor
 * @return the {@link Connection}
 */
public static final <T extends UniversallyUniqueIdentifiable> Connection<T> create(List<T> elements, long first, String after) {
    // Get the limit of this stream which is either the number of elements
    // specified by "first"; otherwise the full elements size
    long limit = first > 0 ? first : elements.size();
    // Create the edges for the connection
    List<Edge<T>> edges = elements.stream().limit(limit).map(element -> new DefaultEdge<>(element, ConnectionCursorUtil.from(element.getId()))).collect(Collectors.toList());
    // Create the page information for the connection
    ConnectionCursor startCursor = ConnectionCursorUtil.getStartCursor(edges);
    ConnectionCursor endCursor = ConnectionCursorUtil.getEndCursor(edges);
    boolean hasPreviousPage = after != null;
    boolean hasNextPage = edges.size() >= first;
    PageInfo pageInfo = new DefaultPageInfo(startCursor, endCursor, hasPreviousPage, hasNextPage);
    return new DefaultConnection<>(edges, pageInfo);
}

Example 2 with DefaultEdge

use of graphql.relay.DefaultEdge in project light-example-4j by networknt.

the class TodoSchemaMutations method createAddTodoMutation.

private void createAddTodoMutation() {
    GraphQLInputObjectField textField = newInputObjectField().name("text").type(new GraphQLNonNull(GraphQLString)).build();
    List<GraphQLInputObjectField> inputFields = Arrays.asList(textField);
    GraphQLFieldDefinition todoEdge = newFieldDefinition().name("todoEdge").type(todoSchema.getTodosEdge()).dataFetcher(environment -> {
        Map source = (Map) environment.getSource();
        String todoId = (String) source.get("todoId");
        Todo todo = todoSchema.getTodo(todoId);
        return new DefaultEdge(todo, todoSchema.getSimpleConnection().cursorForObjectInConnection(todo));
    }).build();
    List<GraphQLFieldDefinition> outputFields = Arrays.asList(todoEdge, getViewerField());
    DataFetcher mutate = environment -> {
        Map<String, Object> input = environment.getArgument("input");
        String text = (String) input.get("text");
        String newId = todoSchema.addTodo(text);
        Map<String, String> result = new LinkedHashMap<>();
        result.put("clientMutationId", (String) input.get("clientMutationId"));
        result.put("todoId", newId);

    addTodo = todoSchema.getRelay().mutationWithClientMutationId("AddTodo", "addTodo", inputFields, outputFields, mutate);
