Valid Json code for elements of Type "Array"

Reinhold.Blank

Hi,

the protocol specification for array primitives is a little bit rare. Therefore I have some questions.

1.) Is the following json sample syntax in case of a UInt- or AsciiString-array also valid?

1. "Elements": {
2. "Name": "ERT_FD3_LF1",
3. "SupportsQoSRange": 0,
4. "Capabilities": {
5. "Type": "Array",
6. "Data": [5,6,10,11,13,18,19]
7. }
8. },
9. 
   
10. "Elements": {
11. "Name": "ERT_FD3_LF1",
12. "SupportsQoSRange": 0,
13. "Capabilities": {
14. "Type": "Array",
15. "Data": ["D1", "D2"]
16. }
17. },

2.) Could a array have a data-property with null, like following?

• "Elements": {
• "Name": "ERT_FD3_LF1",
• "SupportsQoSRange": 0,
• "Capabilities": {
• "Type": "Array",
• "Data": null
• }
• },

3.) or it should be a empty-Array like this:

• "Elements": {
• "Name": "ERT_FD3_LF1",
• "SupportsQoSRange": 0,
• "Capabilities": {
• "Type": "Array",
• "Data": [ ]
• }
• },

The syntax of an Array should be similar in a FieldEntry or ElementEntry. It doesn't support the short form.

{
   "Type": "<Type>",
   "Data": [<Data>]
}

In a FieldEntry, an Array looks like this:

"KEYWD_LIST": {
                "Type": "AsciiString",
                "Data": [
                    "TEST1",
                    "TEST2"
                ] 
            }

In an ElementEntry, an Array looks like this:

"Capabilities": {
  "Type": "Array",
  "Data": {
  "Type": "UInt",
  "Data": [5,6,10,11,13,18,19]
  }
},

The "Type": "Array" is required by an element list and the payload (an array) is specified in the "Data" property.
