unionPendingRequests

  • Edit on GitHub

Group pending requests by the request that they are a subset of.

connection.unionPendingRequests( pendingRequests )

This is called by getListData to determine which pending requests can be unified into a broader request. This produces a grouping of 'parent' sets to 'child' requests whose data will be derived from the data retrieved by the parent.

After this grouping is returned, getListData executes requests for the parent sets. After a parent request succeeds, the child requests will have their data calculated from the parent data.

Parameters

  1. pendingRequests {Array<PendingRequest>}:

    an array of objects, each containing:

    • set - the requested set
    • deferred - a wrapper around a Promise that will be resolved with this sets data

Returns

{Array<Object>}:

an array of each of the unified requests to be made. Each unified request should have:

  • set - the set to request
  • pendingRequests - the array of pending requests the set satisfies

Example

This function converts something like:

[
  {set: {completed: false}, deferred: def1},
  {set: {completed: true}, deferred: def2}
]

to:

[
  {
   set: {},
   pendingRequests: [
     {set: {completed: false}, deferred: def1},
     {set: {completed: true}, deferred: def2}
   ]
  }
]
