How to pass args from class to main method of class that extends runBaseBatch?

Hi ,

I have this dialog :

public void run(Args _args)
{
    
    dialog.run();
        if (dialog.closedOk())
        {
            BatchClass::main(_args);
        }
}

When I click on button "Ok" I want to pass args in the 2end class that extends runBase Batch :

When I click on button Ok , this form will be opening :

public static void main(Args _args)
{
    BatchClass    batchClass;
   
    batchClass = BatchClass::construct();
    batchClass.caption();
    if(batchClass.prompt())
   {
        RoleVersion = _args.record(); //When I run this code on batch the value of 
       // Role version was nul
        RoleVersion.run();
   }
 }

I don't understand why args is null when I run this class in batch.

Main method of the batch class is run only when you launch the batch dialog. When the actual batch process executes it, this method is not run.

So, you need to add all variables that the batch needs in the classDeclaration and [tag:CurrentList] of your batch class. And add a parm method which you can use to pass the variable from main method to the actual class instance after instantiating the class.

I think you can only use simple data types, not table buffers.

Hi,

I dont understand what you means : " And add a parm method which you can use to pass the variable from main method to the actual class instance after instantiating the class."

You need to pass a value to an object, like this:

batchClass = BatchClass::construct(); batch.parmMyValue("whatever");

To be able to do that, you must define the method first (if it doesn't already exist).

Hi Basma,

The main method is a static method where you are instantiating the class which runs the batch process. If you want to pass some values into this class, you need to create a global variable in the class. Then you write a parm method which gets/sets this variable.

For an example, you can take a look at Tutorial_RunBaseBatchForm class.

There is a variable declared - "custAccount". The variable is also included in the CurrentList macro

In the same class, you can check the method parmCustAccount, which can be used for setting the value for custAccount and getting its value as well.

Do, from the main method you could write something like -

batchClass.parmCustAccount("00001");

Thanks ,

I create method that return the values which are packed :

public class RoleBatch extends RunBaseBatch { int64 versionRecId; str _roleNameGlb; int64 roleRecId; RoleVersion _matrixRoleVersion; #define.CurrentVersion(1) #define.Version1(1) #localmacro.CurrentList versionRecId, _roleNameGlb, roleRecId #endmacro }

public void getValues(str _roleName , RoleVersion _roleVersion,Role _eukRole ) { _roleNameGlb = _roleName; select * from _matrixRoleVersion where _matrixRoleVersion.RecId == _roleVersion.RecId; versionRecId = _matrixRoleVersion.RecId; select firstonly RoleGlb where RoleGlb.RecId== _eukRole.RecId; roleRecId = RoleGlb.RecId; }

in the main method of class that extends runbaseBatch :

public static void main(Args _args) { RoleBatch generateSecurityRole; RoleVersion eukMatrixRoleVersion; Role eukRole; RoleCreateRole roleCreateRole; MatrixRole MatrixRole = null; Args argsGenerationFromMatrix; str roleName; str CompanyId; utcDateTime dateTime = DateTimeUtil::utcNow(); ; CompanyId = CompanyInfo::Find().DataArea; generateSecurityRole = RoleBatch::construct(); generateSecurityRole.caption(); if(generateSecurityRole.prompt()) { eukMatrixRoleVersion = _args.record(); eukMatrixRoleCreateRole = MatrixRoleCreateRole::constructFromArgs(_args); eukMatrixRole = eukMatrixRoleCreateRole.eukMatrixRole(); select firstonly eukRole where eukRole.RelatedMatrix == eukMatrixRole.MatrixID; if (eukRole) { roleName = eukRole.Name; } else { roleName = CompanyId "-" eukMatrixRole.MatrixName; } info(roleName); info(int642str(eukMatrixRoleVersion.RecId)); generateSecurityRole.getValues(roleName,eukMatrixRoleVersion,eukRole); generateSecurityRole.run(); } }

I use your suggestion in the main method of class that extends runBaseBatch or the first class?

Hi Basma,

I thought you had only one class. It should be in the main of the class extending RunBaseBatch.

Not sure why you have another class though.

I have the first class from it I want to get values :

class MatrixRoleCreateRoleDialog { //this is the first class from it I want to get values }

public void run(Args _args) { dialog.run(); if (dialog.closedOk()) { //I want to pass values to class extending runbaseBatch RoleBatch::main(_args); } }

By the way, I think you were trying to implement similar functionality using SysOperation about 1-2 weeks ago, but using a different username Just "Basma" instead of "Basma WED". Any particular reason why you abandoned that code and are now trying to implement it via RunBaseBatch?

I think we were discussing the exact same question - how to pass some value from caller class to your batch. And as far as I remember we demonstrated to you how to do it. But now you have changed the framework and are dealing with the same problem again.

First of all, you should try to split your problem in small parts. Then solve one part at a time. Also jumping between different frameworks (SysOperation and RunBaseBatch) might not be productive, instead I recommend trying to learn to understand one of them first. Once you understand the concepts and can effortlessly develop functionalities using one of the frameworks, it should be easy to learn the other. But if you have difficulties with understanding the fundamentals, you are just making your life more difficult if you jump between them.

Your first part is passing values from class to another. This has nothing to do with batches!

I thought you already managed to pass values from one class to another, and your only problem was to use them in batch. But apparently even your first part is not working yet. So please forget the batch for now and only resume once you have completed the first part.

For the first part, here are the required steps:

Put this in the first class:

public void run(Args _args) { dialog.run(); if (dialog.closedOk()) { Args args = new Args(); args.caller(this); //I want to pass values to class extending runbaseBatch RoleBatch::main(args); } }

By the way, I don't know what is in "_args" parameter of the run method, and I don't know if you have something valuable there. I assume that you don't have anything there that is needed in the batch class, so I'm instantiating a new Args object and passing "this" (=pointer to the current class) into it.

In your second class (the batch class) you can access any methods of the caller class from the main method of your batch class:

public static void main(Args _args) { MyFirstClass myFirstClass = _args.caller(); // Now you can call any methods of myFirstClass to fetch values from it string myString = myFirstClass.getMyString(); }

Hi,

we are two colleagues working on the same task, she tried the sysoperation framework, and I tried with runBaseBatch.

But we are both stuck with the batch.

For information , If run my class without batch I haven't any problem.

But when I use the batch , I can't get any values
