The connection doesn’t receive outside arguments, so the list of items
Given a list of items and a new item, it will provide a connection and an edge.
This provides some isolation from ‘GraphQL::Relay` internals.

def initialize(collection:, item:, parent: nil, context: nil, edge_class: nil)

Parameters:
  • edge_class (Class) -- The class to wrap `item` with (defaults to the connection's edge class)
  • context (GraphQL::Query::Context) -- The surrounding `ctx`, will be passed to the connection if provided (this is required for cursor encoders)
  • parent (Object) -- The owner of `collection`, will be passed to the connection if provided
  • item (Object) -- The newly-added item (will be wrapped in `edge_class`)
  • collection (Object) -- The list of items to wrap in a connection 
def initialize(collection:, item:, parent: nil, context: nil, edge_class: nil)
  if context && context.schema.new_connections?
    conn_class = context.schema.connections.wrapper_for(collection)
    # The rest will be added by ConnectionExtension
    @connection = conn_class.new(collection, parent: parent, context: context, edge_class: edge_class)
    # Check if this connection supports it, to support old versions of GraphQL-Pro
    @edge = if @connection.respond_to?(:range_add_edge)
      @connection.range_add_edge(item)
    else
      @connection.edge_class.new(item, @connection)
    end

    connection_class = BaseConnection.connection_for_nodes(collection)
    @connection = connection_class.new(collection, {}, parent: parent, context: context)
    edge_class ||= Relay::Edge
    @edge = edge_class.new(item, @connection)
  end
  @parent = parent
