Description Thekepat Sudesh CLA 2004-07-23 19:35:55 EDT 
Like Intellij (IDEA) have class inheritance indicators on the first line of 
class declaration (on the left ruler) . Clicking on the arrow gives the list of 
classes that inherit from this class

>classes that inherit from this class
So you mean subtypes - right?
Comment 2 Thekepat Sudesh CLA 2004-07-26 07:22:00 EDT 
Yes. A downward arrow (like a upward arrow indicating overidden functions).
Thanks.
Comment 3 Dani Megert CLA 2004-07-26 08:22:22 EDT 
Getting the subtypes can be quite expensive.
We could do it even on the method level.
Comment 4 Thekepat Sudesh CLA 2004-07-26 23:30:14 EDT 
If class A has two direct subclasses B & C, as shown :
(<indicator goes here>)  class A {}
class B extends A {}
class C extends A {}
Now just like you have an function override indicator (indicating that a 
virtual function has been overriden (an upward arrow) we could have a downward 
arrow to indicate the direct subclasses of A...Just like what IDEA (Intellij) 
has.
Thanks.
