GetJsonArray( ) method (JsonObject)

Gets the JsonArray value of the named property.

Return type:

Progress.Json.ObjectModel.JsonArray class

Access:

PUBLIC

Applies to:

Progress.Json.ObjectModel.JsonObject class

 

Syntax 

GetJsonArray( INPUT property-name AS CHARACTER )

property-name

A JsonError is raised if:

property-name is the empty string (""), or is the Unkown value (?)

The property does not exist

The property value is not a JsonArray

The following example demonstrates the functionality of the GetJSonArray( ) method.

The following is a sample JsonObject:

 

{   “CustOrder”: {     “CustNum”: 1,     “Name”: “Lift Tours”,     “NewCust”: false,     “ttOrder”: [       {“OrderNum”: 82, “OrderDate”: “2010-09-20”},       {“OrderNum”: 83, “OrderDate”: “2010-09-20”} ] } }

The following is a code fragment that uses the GetJsonArray( ) method:

 

DEFINE VARIABLE CustInfo AS LONGCHAR NO-UNDO. DEFINE VARIABLE myObj AS JsonObject NO-UNDO. DEFINE VARIABLE myArray AS JsonArray NO-UNDO. DEFINE VARIABLE myLongchar as LONGCHAR NO-UNDO.   /* . . Set CustInfo to JsonObject shown above. . */   myObj = CAST(myParser:Parse(CustInfo), JsonObject). myArray = myObj:GetJsonObject(“CustOrder”):GetJsonArray(“ttOrder”). myArray:Write(myLongchar, TRUE).

The following is the resulting myLongchar value:

 

[ {“OrderNum”: 82, “OrderDate”: “2010-09-20”}, {“OrderNum”: 83, “OrderDate”: “2010-09-20”} ]
