X++ list of Maps

I am going to be reading some data from a file, and I would like to make a method that reads all the lines from the file and saves them in a variable to return from the method.

The problem is that each line in the file might not have the same fields every time, but it does contain [FieldName, Value]

So I have used a Map to hold one line from the file at a time, and that works.

But now my problem is, where should I store all the Map variables per line that I get?

Anyone have an idea?

RE: X++ list of Maps

Use the Array foundation class.

static void Job186(Args _args)

{

Array oArray = new Array (Types::Class);

Map iMap = new Map(Types::Integer,Types::String);

Map getmap;

MapEnumerator gmE;

iMap.insert(1,"Hest");

iMap.insert(2,"Fest");

iMap.insert(3,"Pest");

oArray.value(1,iMap);

iMap = new Map(Types::Integer,Types::Date);

iMap.insert(1,18\01\1971);

iMap.insert(2,24\12\2015);

iMap.insert(3,01\06\2015);

oArray.value(2,iMap);

getMap = oArray.value(1);

gmE = getmap.getEnumerator();

gmE.moveNext();

gmE.moveNext();

print gmE.currentValue();

getMap = oArray.value(2);

gmE = getmap.getEnumerator();

gmE.moveNext();

gmE.moveNext();

gmE.moveNext();

print gmE.currentValue();

pause;

}

RE: X++ list of Maps

Typical, a short time sending the question here, I find the solution.

I was trying to save the Map in a List but since I was using a List of Types::AnyType it did not work, but with a List of Types::Class it worked.
