public virtual object Clone()

'Declaration
 
Public Overridable Function Clone() As Object

'Usage
 
Dim instance As BarcodeData
Dim value As Object
 
value = instance.Clone()

public virtual object Clone()

ObjectiveC Syntax

 function Leadtools.Barcode.BarcodeData.Clone()

public:
virtual Object^ Clone();

Return Value

The BarcodeData method creates, and casts the barcode as an object.

This methods clones (creates a new object) of the byte array that represents that data obtained from GetData. This data will not be shared between this BarcodeData and the object that is returned.

However, Tag is user defined value and BarcodeData does not have rules to dictate what action to perform when the object is cloned. Therefore, this method will simply set the Tag property of the returned object to the value in the source object. It is up to the user to change this behavior.
