Type: Procedure

Parameters

Parameter	Type	Description
data	Struct	Data to convert to JSON

Syntax

Procedure DataTypeToJson Struct data

Call Example

Send DataTypeToJson data

Description

Converts a native DataFlex variable (usually a struct / array) into a JSON object structure representing that data.

This can be used to serialize struct data into a JSON string, where DataTypeToJson would be followed by a Stringify call returning the actual string.

The Name meta-data tag allows you to designate an alternate name to Struct members that is used when serializing and deserializing structs to and from JSON and XML.

Sample

This sample code shows how to give an external name of "Number" to a struct member that is a reserved word in DataFlex.

Struct tMyStruct
    Integer iItemId
    { Name="Number" }
    Integer iQuantity
End_Struct

Function GenerateJson Returns String
    Handle hoJson
    tMyStruct data
    String sResult

    Get Create (RefClass(cJsonObject)) to hoJson

    Move 24 to data.iItemId
    Move 5 to data.iQuantity
    Send DataTypeToJson of hoJson data

    Set peWhiteSpace of hoJson to jpWhitespace_Spaced
    Get Stringify of hoJson to sResult
    Send Destroy of hoJson

    Function_Return sResult
End_Function

Generates the following JSON:

{ "iItemId": 24, "Number": 5 }
