 | TResultPointEventObject | |
| TResultPointHelpers | in order to implement TResultPoint as an interface all static methods have been moved in this static class. this class contains also the CreateResultPoint method that must be used in place of the actual class constructor |
| Name | Description | |
|---|---|---|
 | IResultPoint | To mimic "garbage collection" (or ARC) with old-gen compilers we have to use interfaces. IResultPoint is the interface that maps TResultPoint which is now implemented as a TInterfacedObject descendant which supports automatic deallocation based on reference counting of interface variables. See ZXing.ResultPointImplementation to see the actual implementation of this interface. since we are using automatic reference counting, we don't need the Clone method any more. |

 | TResultPointCallback | Callback which is invoked when a possible result point (significant point in the barcode image such as a corner) is found. |
