How to get the fields definition of an InfoTable

[pruby]

Is it possible to get the field definition of an InfoTable prior to knowing its DataShape?

I am currently doing it by converting my InfoTable to json and then by taking the dataShape definition:

var fields = Resources["InfoTableFunctions"].ToJSON(params);
var result = fields.dataShape.fieldDefinitions;

This works fine but I'm wondering if there is a nicer way to do this, by using services like getDataShape and GetFieldDefinitions.

There was a similar thread to this before.

I think you can just do something like

for each (var field in myinfotable.fields)

The correct way of recovering the Fields of an Infotable with and unknown DataShape it's this one:

var iLF ;
if ((myInfotable.dataShape==null)||(myInfotable.dataShape==undefined)) {
   iLF = myInfotable.ToJSON().dataShape.fieldDefinitions;
 } else {
   iLF = myInfotable.dataShape.fields;
 }
for (var key in iLF) {
 logger.info("Field Name "+key+" baseType: "+iLF[key].baseType);
}
