Struct FSCEXPEXT@1.1001:JSONStructFormat

Formatting information for object classes or types, used with Value2JSON.

When generating JSON an object or an aggregate, the supplied format list is consulted. If the type of the value matches jsftype, the remaining properties specify how to format the JSON entry. If FSCEXPEXT@1.1001:jssimple is true, for object classes just the object address is generated, otherwise the property list from FSCEXPEXT@1.100:jsfproperties specifies the properties of the sub entry.

The following sample generates a list of two users in different JSON formats.

  JSONPropertyFormat[] properties = [
    { jpfattrdef: #usersurname, jpfname: "FamilyName" },
    { jpfattrdef: #userfirstname, jpfname: "FirstName" }
  ];
  JSONStructFormat[] simpleformat = [
    { jsftype: #User, jsfsimple: true }
  ];
  JSONStructFormat[] complexformat = [
    { jsftype: #User, jsfproperties: properties }
  ];


  User[] users = FROM User u WHERE u.userlogname like '%0001%';
  User[] twousers = [users[0], users[1]];
  dictionary data;
  data.users = twousers;
  string standardJSON = cooobj.Value2JSON(twousers);
  string simpleJSON = cooobj.Value2JSON(twousers, , , simpleformat);
  string complexSON = cooobj.Value2JSON(twousers, , , complexformat);
  string dataJSON = cooobj.Value2JSON(data, , , complexformat);

result in the following JSON strings

standardJSON = [
  {"objaddress":"COO.1.506.1.1000074","objname":"Baumann0001 Christina"},
  {"objaddress":"COO.1.506.1.1000077","objname":"Owner0001 Michael"}
]
simpleJSON = [
  {"objaddress":"COO.1.506.1.1000074"},
  {"objaddress":"COO.1.506.1.1000077"}
]
complexJSON = [
  {"FamilyName":"Baumann0001", "FirstName":"Christina"},
  {"FamilyName":"Owner0001","FirstName":"Michael"}
]
dataJSON = {
  "users": [
   {"Family Name":"Baumann0001","First Name":"Christina"},
   {"Family Name":"Owner0001","First Name":"Michael"}
  ]
}
