      public SIP_Character_SIS node(graphql.schema.DataFetchingEnvironment dataFetchingEnvironment, SIP_CharacterEdge_SIS origin)
      Description copied from interface: DataFetchersDelegateCharacterEdge
      This method loads the data for CharacterEdge.node.
      Specified by:
      node in interface DataFetchersDelegateCharacterEdge
      Parameters:
      dataFetchingEnvironment - The GraphQL DataFetchingEnvironment. It gives you access to the full GraphQL context for this DataFetcher
      origin - The object from which the field is fetch. In other word: the aim of this data fetcher is to fetch the node attribute of the origin, which is an instance of {InterfaceType {name:CharacterEdge, fields:{Field{name:node, type:Character, params:[]},Field{name:cursor, type:String!, params:[]}}, comments ""}. It depends on your data modle, but it typically contains the id to use in the query.

      public CompletableFuture<SIP_Character_SIS> node(graphql.schema.DataFetchingEnvironment dataFetchingEnvironment, org.dataloader.DataLoader<UUID,SIP_Character_SIS> dataLoader, SIP_CharacterEdge_SIS origin)
      Description copied from interface: DataFetchersDelegateCharacterEdge
      This method loads the data for CharacterEdge.node.
      For optimization, this method returns a CompletableFuture. This allows to use graphql-java java-dataloader to highly optimize the number of requests to the server.
      The principle is this one: The data loader collects all the data to load, avoid to load several times the same data, and allows parallel execution of the queries, if multiple queries are to be run.
      You can implements this method like this: 
      

      

      Specified by:
      

      node in interface DataFetchersDelegateCharacterEdge
      

      Parameters:
      

      dataFetchingEnvironment - The GraphQL DataFetchingEnvironment. It gives you access to the full GraphQL context for this DataFetcher
      

      dataLoader - The DataLoader allows to load several data in one query. It allows to solve the (n+1) queries
            issues, and greatly optimizes the response time.

      origin - The object from which the field is fetch. In other word: the aim of this data fetcher is to fetch the node attribute
    of the origin, which is an instance of {InterfaceType {name:CharacterEdge, fields:{Field{name:node, type:Character, params:[]},Field{name:cursor, type:String!, params:[]}}, comments ""}. It depends on your data modle, but it typically contains 
    the id to use in the query.
