What is shadowing
What is shadowing ?
✍: Guest
When two elements in a program have same name, one of them can hide and shadow the
other one. So in such cases the element which shadowed the main element is referenced.
Below is a sample code, there are two classes “ClsParent” and “ClsShadowedParent”. In
“ClsParent” there is a variable “x” which is a integer. “ClsShadowedParent” overrides
“ClsParent” and shadows the “x” variable to a string
Public Class ClsParent Public x As Integer End Class Public Class ClsShadowedParent Inherits ClsParent Public Shadows x As String End Class
