Acumatica - 覆盖业务逻辑，访问受保护的方法

提问于

我想要覆盖业务逻辑中SOInvoiceEntry图的InvoiceOrder逻辑，因此如果未选择“Bill Separately'选项，我可以更改聚合发票的逻辑 .

我在下面编写了一个扩展方法来替换内置的InvoiceOrder方法 .

public delegate void InvoiceOrderDelegate(DateTime invoiceDate, PXResult<SOOrderShipment, SOOrder, CurrencyInfo, SOAddress, SOContact, SOOrderType> order, PXResultset<SOShipLine, SOLine> details, Customer customer, DocumentList<ARInvoice, SOInvoice> list);

[PXOverride]
public virtual void InvoiceOrder(DateTime invoiceDate, PXResult<SOOrderShipment, SOOrder, CurrencyInfo, SOAddress, SOContact, SOOrderType> order, PXResultset<SOShipLine, SOLine> details, Customer customer, DocumentList<ARInvoice, SOInvoice> list, InvoiceOrderDelegate baseMethod)
{
    //Do Stuff
}

我'm unsure how to access the original object'的受保护方法 . 通常我只是调用 Base.DoSomething(); ，但我认为我无法访问受保护的方法，因为扩展对象不是直接从SOInvoiceEntry派生的 .

我是否还需要覆盖我想要使用的受保护方法，或者是否有办法从扩展中访问它们？

任何帮助都是极好的 .

谢谢 .

    您使用传递给方法的委托作为基本调用 . 对于InvoiceCreated，您应该能够覆盖它并调用它，如下所示：

    public class SOInvoiceEntryExtension : PXGraphExtension<SOInvoiceEntry>
{
    public delegate void InvoiceOrderDelegate(DateTime invoiceDate, 
        PXResult<SOOrderShipment, SOOrder, CurrencyInfo, SOAddress, SOContact, SOOrderType> order, 
        PXResultset<SOShipLine, SOLine> details, 
        Customer customer, 
        DocumentList<ARInvoice, SOInvoice> list);

    [PXOverride]
    public virtual void InvoiceOrder(DateTime invoiceDate, 
        PXResult<SOOrderShipment, SOOrder, CurrencyInfo, SOAddress, SOContact, SOOrderType> order, 
        PXResultset<SOShipLine, SOLine> details, 
        Customer customer, 
        DocumentList<ARInvoice, SOInvoice> list, 
        InvoiceOrderDelegate baseMethod)
    {
        //Code before
        baseMethod?.Invoke(invoiceDate, order, details, customer, list);
        //Code after

        // This also works, but the delegate should be used.
        //Base.InvoiceOrder(invoiceDate, order, details, customer, list);

        //InvoiceCreated(someInvoice, someSource);
    }

    [PXOverride]
    public  virtual void InvoiceCreated(ARInvoice invoice, SOOrder source, SOInvoiceEntry.InvoiceCreatedDelegate baseMethod)
    {
        baseMethod?.Invoke(invoice, source);
    }
}
