81) How to use the signature using Disposable context ( Store value in global catch)

-

  I had a scenario where I need to Store the value in the gobal value and use it some where .


The challenge is that i need to store the value because there is standard process going and in between i need to put my code 


Step 1-  Create a class that will hold the global caches 


public final class AvaEntWorkOrderAdjustParameter implements System.IDisposable

{

    private static  AvaEntWorkOrderAdjustParameter instance;

    Public  str     formCallerName;

    

    Public  boolean                ExpectedEndGroup;

    Public  boolean                MoveExpectedEndGroup;

    public  EntAssetWorkOrderTable callerWorkOrderTable;

    public  NumberOfDays           MoveExpectedEnd;

    public  EntAssetExpectedEnd    ExpectedEnd;


    protected void new() 

    {

        if (instance)

        {

            throw Error(Error::wrongUseOfFunction(funcName())); 

        }


        instance = this;


        formCallerName       = "";

        ExpectedEndGroup     = NoYes::No;

        MoveExpectedEndGroup = NoYes::No;

        MoveExpectedEnd      = 0;

        ExpectedEnd          = utcDateTimeNull();


    }


    public static AvaEntWorkOrderAdjustParameter construct()

    {

        return new AvaEntWorkOrderAdjustParameter();

    }


    /// <summary>

    /// Disposes of the current instance of this class.

    /// </summary>

    public void dispose()

    {

        instance = null;

    }


    /// <summary>

    /// Gets the current instance of this class.

    /// </summary>

    /// <returns>The current instance of this class.</returns>

    public static AvaEntWorkOrderAdjustParameter current()

    {

        return instance;

    }


}


+=====================================================================


Step 2 :- Create a extension of the form where we need to store the value 


public void closeOk()

    {

        AvaEntWorkOrderAdjustParameter  avaEntWorkOrderAdjustParameter; 


        DialogButton                    dialogButton;

        boolean                         createSeqWorkOrder = EntAssetMaintenancePlan::find(AvaEntAssetMaintenanceProgram::findRecId(callerWorkOrderTable.AvaMaintenanceProgram).MaintenancePlan).AvaSequentialWorkOrderDate;

       

        if( callerFormName == formStr(AvaEntAssetMaintenanceProgram) && ExpectedEndGroup.optionValue() & this.validateFields() && createSeqWorkOrder)

        {

            if((MoveExpectedEnd.value() >= 0) && (ExpectedEnd.dateTimeValue() >= callerWorkOrderTable.ExpectedEnd))

            {


                dialogButton = Box::yesNo("@AvaTransMountain:AvaWorkorderDateUpdateDIalog_Label", DialogButton::Yes, "@AvaTransMountain:AvaWorkorderUpdate_Label");


                if(dialogButton == DialogButton::Yes)

                {

                    avaEntWorkOrderAdjustParameter = AvaEntWorkOrderAdjustParameter::construct();

                   

                    avaEntWorkOrderAdjustParameter.formCallerName       =  callerFormName;

                    avaEntWorkOrderAdjustParameter.ExpectedEndGroup     =  ExpectedEndGroup.optionvalue();

                    avaEntWorkOrderAdjustParameter.MoveExpectedEndGroup =  MoveExpectedEndGroup.optionvalue();

                    avaEntWorkOrderAdjustParameter.callerWorkOrderTable =  callerWorkOrderTable;

                    avaEntWorkOrderAdjustParameter.MoveExpectedEnd      = MoveExpectedEnd.value();

                    avaEntWorkOrderAdjustParameter.ExpectedEnd          = ExpectedEnd.dateTimeValue();

                }

            }

        }


        next closeOk();

       


        if (avaEntWorkOrderAdjustParameter::current())

        {

            avaEntWorkOrderAdjustParameter.dispose();

            info("@AvaTransMountain:AvaDatesUpdate_Infolog");

        }

     

    }


========================================================================

Step 3 :- Create a extension of the class where we want to use this global cache value and release it here 


[ExtensionOf(classStr(EntAssetWorkOrderTableAdjust))]

final class AvaEntAssetWorkOrderTableAdjustCls_Extension

{

    private  EntAssetWorkOrderTable      avaWorkOrderTable;

    private int avaWorkOrderCount;

    private int adjustedDays;

    private int workOrderLineAdjustedDays;

    #define.MaxWorkOrders(30)

    public void run()

    {


        AvaEntWorkOrderAdjustParameter  EntWorkOrderAdjustParameter = AvaEntWorkOrderAdjustParameter::current();

        EntAssetExpectedStart expectedEndOrig;


        if (EntWorkOrderAdjustParameter)

        {

            expectedEndOrig = EntWorkOrderAdjustParameter.callerWorkOrderTable.ExpectedEnd;

        }


        next run();


        avaWorkOrderCount++;


        if (EntWorkOrderAdjustParameter)

        {

            if(!avaWorkOrderTable)

            {

                avaWorkOrderTable = EntWorkOrderAdjustParameter.callerWorkOrderTable;

                avaWorkOrderTable.reread();


                 EntAssetExpectedStart expectedEndCurrent = avaWorkOrderTable.ExpectedEnd;


                 TransDate   NewEndDate     = DateTimeUtil::date(expectedEndCurrent);

                 TransDate   oldEndDate     = DateTimeUtil::date(expectedEndOrig);


                 adjustedDays = (NewEndDate - oldEndDate); 

            }

           


            if (adjustedDays > 0)

            {

                EntAssetWorkOrderTable workOrderTableNextLocal;


                TransDate   NewEndDateWorkOrderLine;

                TransDate   oldEndDateWorkOrderLine;


                 avaWorkOrderTable.reread();


                 select firstonly forupdate workOrderTableNextLocal

                    order by workOrderTableNextLocal.WorkOrderId

                    where workOrderTableNextLocal.AvaMaintenanceProgram == avaWorkOrderTable.AvaMaintenanceProgram

                    && workOrderTableNextLocal.WorkOrderId > avaWorkOrderTable.WorkOrderId;


                if (workOrderTableNextLocal && avaWorkOrderCount<#MaxWorkOrders)

                {

                    if(EntWorkOrderAdjustParameter.MoveExpectedEndGroup)

                    {

                        NewEndDateWorkOrderLine     = DateTimeUtil::date(avaWorkOrderTable.ExpectedEnd);

                        oldEndDateWorkOrderLine     = DateTimeUtil::date(workOrderTableNextLocal.ExpectedStart);


                        workOrderLineAdjustedDays = (NewEndDateWorkOrderLine - oldEndDateWorkOrderLine);


                        moveExpectedStart     = true;

                        moveExpectedStartDays = workOrderLineAdjustedDays;//adjustedDays;

                        moveExpectedEnd       = true;

                        moveExpectedEndDays   = workOrderLineAdjustedDays;//adjustedDays;

                    }

                    else

                    {

                        NewEndDateWorkOrderLine     = DateTimeUtil::date(avaWorkOrderTable.ExpectedEnd);

                        oldEndDateWorkOrderLine     = DateTimeUtil::date(workOrderTableNextLocal.ExpectedStart);


                        workOrderLineAdjustedDays = (NewEndDateWorkOrderLine - oldEndDateWorkOrderLine);



                        newExpectedStart =  true;

                        expectedStart    =  avaWorkOrderTable.ExpectedEnd;//DateTimeUtil::addDays(avaWorkOrderTable.ExpectedStart, adjustedDays);

                        newExpectedEnd   =  true;

                        expectedEnd      =  DateTimeUtil::addDays(workOrderTableNextLocal.ExpectedEnd, workOrderLineAdjustedDays);

                    }


                    workOrderSet = new Set(Types::Int64); 

                    workOrderSet.add(workOrderTableNextLocal.RecId); 

                    newServiceLevel = false;

                    newResponsible = false;


                    avaWorkOrderTable.data(workOrderTableNextLocal);

                    

                    this.run();

                }

            }

        }

    }


}
