Support for modeling queues and lists

[Dirk Bolte]

Proposal

Reported by: @ioanngolovko

In order to support modeling collections and messaging queues a new data container should be added. The current approach only has one state with CRUD operations. Adding a dynamic list is challenging.

Idea is to add a new container: list. The syntax can look like this:

• serveEventListeners
  • recordState

  {
    "context": "...",
    "list": {
      "addLast": {
        "stateValue": "..."
      },
      "addFirst": {
        "stateValue": "..."
      }
    }

  • deleteState

    {
      "context": "...",
      "list": {
        "deleteFirst": true,
        "deleteLast": true,
        "deleteIndex": 1,
        "deleteWhere": {
          "property": "...",
          "value": "...",
    }

• response

  {
   "jsonBody": {
      "id": "{{state context=... list.last='id'}}",
      "firstName": "{{state context=... list.first='firstName'}}",
      "lastName": "{{state context=... list.[1]='lastName'}}"
    }
  }

Templating will be supported for all values.

Syntax for recordState and deleteState is as described.

For Response Templating, the syntax had to be adapted:

{
 "jsonBody": {
    "id": "{{state context=... list.last='id'}}",
    "firstName": "{{state context=... list='[0].firstName'}}",
    "lastName": "{{state context=... list='[-1].lastName'}}"
  }
}
