Type of variable in declaration

Posted on by Community Member

I want to find out the type of a variable's name which is a string. There probably must be a function like this, but I cannot find it.

I expect to work it like this:

str input;

anytype result;

;

input = "SysSetup";

result = function(input); // returns "class", probably string or enum

input = "AgreementReference";

result = function(input); // returns "table"

input = "ABC";

result = function(input); // returns "base enum"

etc.

Maybe you can use

typeOf(yourvariable)

Thanks, but it doesn't work.

If typeof function recieves string, it returns "String". If it would be possible to convert this string to Object and get type of that object, then it would probably work.

You can use utilelements table as follow:

#AOT

UtilElements utilElements;

UtilIdElements utilIdElements;

DictField df;

DictTable dt;

TreeNode tn;

int counter = 0;

while

select utilElements

where utilElements.name == "SysSetup"

{

info(strFmt("%1",utilElements.recordType));

}

Hi.

There seem to be a few flaws in your question.

1. Your code seems to want to actually instantiate the type to a variable rather than simply retrieve the name of the type (which would typically be a string)

2. It seems like you want to figure out the type from a simple Name. This is illogical as there can be different objects in the AOT with the same name. E.G. Forms can have the same names as classes or tables.

Can you maybe expand on what you would like to do?

I think I finally got what you're trying to do. I would simply look into modelstore:

public static UtilElementType getElementType(UtilElementName _name) { SysModelElement modelElement; UtilElementType elementType; select ElementType from modelElement where modelElement.Name == _name && ( modelElement.ElementType == UtilElementType::Table || modelElement.ElementType == UtilElementType::Class || modelElement.ElementType == UtilElementType::ExtendedType || modelElement.ElementType == UtilElementType::Enum); elementType = modelElement.ElementType; return elementType; } // Usage info(enum2str(Test::getElementType('SysSetup')));

It works all right as long as it's restricted to types, because there can't be two types with the same name. Forms, for example, aren't types and can't be used in variable declaration.

Thanks Martin.

I see now they did explicitly talk about a variable's type. I just included that comment as additional info just in case.
