Convert Interface to Abstract Class refactoring
ReSharper_Function2Indexer
This refactoring converts interfaces into abstract classes thus helping you quickly change hierarchical dependency among a set of classes and interfaces.
Consider the following example:
Before refactoring | After refactoring |
---|---|
interface Shape
{
double Area { get; }
void Draw();
}
class Circle : Shape
{
private readonly int radius;
public double Area
{
get {
return Math.PI*Math.Pow(radius, 2);
}
}
public void Draw()
{
//do something
}
}
|
abstract class Shape
{
public abstract double Area { get; }
public abstract void Draw();
}
class Circle : Shape
{
private readonly int radius;
public override double Area
{
get {
return Math.PI*Math.Pow(radius, 2);
}
}
public override void Draw()
{
//do something
}
}
