Saving a var in private class member

**miamimike** · December 10th, 2022, 06:39 PM

Hi, sorry for the simple question but I am stuck.

I am upgrading from one API to a new API.

In the old app the var I was interested in was

int totalQuantity;

I could change its value with

parent.totalQuantity = 5;

Now the API has changed and it is part of a class defined as:

private Decimal m_totalQuantity = Decimal.INVALID;

It has a setter method

public Decimal totalQuantity() { return m_totalQuantity; }

I cannot figure out how to set this var and have tried:
order.totalQuantity(Decimal(1));/
order.totalQuantity(Decimal.valueOf(5));

How do I change the value of the private totalQuantity var????

Thank you for your help.

That's not a setter, that's a getter. You can tell the difference because it takes no inputs and returns an output.
And it's there specifically to prevent you from fiddling with the variable m_totalQuantity, which presumably is a calculated value.
