How to use Accessor (parm) methods?

(0) ShareShare

Posted on by saman0suke 2,890

Hi, I'm trying to use Parm methods to store a variable in a method in class A, and I want to get that value in a method in class B, however, when I try to get the value, it comes empty, I'm not really familiar with Parm methods, could you help me out? this is what I have right now:

public InventTransferId parmInventTransferId(InventTransferId _inventTransferId = inventTransferId)
{
inventTransferId = _inventTransferId;

return inventTransferId;
}

I use parmInventTransferId("value") in class A, and I try to get the value back in class B by using inventParmInventTransferId() but I get nothing, I set the parm method in the class where I'm trying to receive the value, and also in a separated class, but the result is the same, could you help me out please? thanks!!

    Hi,

    Yes, your finding is correct. If you assigned a value to instance A of WMSShipmentReservation, the value only exists in instance A.

    Have you found out why is there another instance of WMSShipmentReservation?

    Ok, I got what the problem is, after my instantiation of the class that contains the parm method, there is another instance that makes my value to get lost, I could use that instance, however, at that point the value that I need is no longer available, is there any other way to do this?

    I'm using two existing classes, abstract class InventTransferUpd extendas UpdateBase, this is the one where I create a new instance of the class WMSShipmentReservation, where I have the parm method declared, something like this:

    WMSShipmentReservation wmsShipReservation = new WMSShipmentReservation();

    wmsShipReservation.parmInventTransferId("value");

    WMSShipmentReservation extends RunBase, I call the parm method like this:

    str value = this.parmInventTransferId();

    But I get nothing, I see that in WMSShipmentReservation class there are two methods, pack and unpack:

    public container  pack()

    {

       return conNull();

    }

    public boolean  unpack(container  packedClass)

    {

       return true;

    }

    Thanks in advanced!

    RE: How to use Accessor (parm) methods?

    As a short answer to how the parm methods are used, I'd like to add the following.

    classB.parmInventTransferId('Value') works like a normal Setter.

    classB.parmInventTransferId() works like a normal Getter.

    As Tommy suggests you may be missing packing/unpacking if one of your classes is a RunBase class. It would be beneficial if we could get to see more of your code.

    Have you implemented the pack-unpack pattern?

    Probably the instance of classA which calls the parmInventTransferId("value") is different from the instance of ClassA which you are calling from ClassB to get the value .

    If the instance is same you will get the value.
