    • getRequestedFields

      public static Map<String,List<String>> getRequestedFields(graphql.schema.DataFetchingEnvironment environment)
      Returns a map of requested fields where the key is the field name and the value is a list of its subfields.

      This is useful to select only the fields that are requested by the client, which can be used to reduce the amount of data that needs to be retrieved from the database.

      For example, if the client requests the following fields: 

       {
   media {
     id
     title
     genres {
       name
     }
   }
 }
      This method will return a map like this: 
       {
   "media": [
     "id",
     "title",
     "genres"
   ],
   "genres": [
     "name"
   ]
 }

      This can be used to create a JPA query that only selects the requested fields, which can improve performance.

      Parameters:
      environment - the DataFetchingEnvironment that contains information about the fields that were requested by the client
      Returns:
      a map of requested fields

    • getPageable

      public static org.springframework.data.domain.Pageable getPageable(graphql.schema.DataFetchingEnvironment dataFetchingEnvironment)
      Returns a Pageable object based on the "page" and "size" arguments of the given DataFetchingEnvironment.

      If the "page" argument is not provided, it defaults to 0. If the "size" argument is not provided, it defaults to 10.

      The returned Pageable object can be used to construct a JPA query that will return the requested page of data.

      Parameters:
      dataFetchingEnvironment - the DataFetchingEnvironment that contains the "page" and "size" arguments
      Returns:
      a Pageable object
