Create Descendant (with virtual overrides)
- 2 minutes to read
In This Article
Creates a descendant class, providing implementation stubs for abstract and virtual members of a base class. Selects the contents of the last generated descendant member, and drops a marker onto the base class declaration.
#Availability
From the context menus or via shortcuts:
- when the edit cursor or caret is on a class name within its declaration.
#Notes
If a base class contains abstract or virtual members, their implementation stubs will be added to a descendant class.
#Example
abstract class │TestClass
{
public int Doubler(int param)
{
return param*2;
}
public virtual string GetCaption()
{
return "Caption";
}
public abstract int Multiply(int param);
}
Public MustInherit Class │TestClass
Public Function Doubler(ByVal param As Integer) As Integer
Return param * 2
End Function
Public Overridable Function GetCaption() As String
Return "Caption"
End Function
Public MustOverride Function Multiply(ByVal param As Integer) As Integer
End Class
Result:
private class TestClassDescendant : TestClass
{
public TestClassDescendant()
{
throw new NotImplementedException();
}
public override string GetCaption()
{
return base.GetCaption();
}
public override int Multiply(int param)
{│throw new NotImplementedException();
}
}
abstract class TestClass
{
public int Doubler(int param)
{
return param * 2;
}
public virtual string GetCaption()
{
return "Caption";
}
public abstract int Multiply(int param);
}
