Is the * the equivalent of Emily Litella's "Never Mind!"
http://en.wikipedia.org/wiki/Emily_Litella
There's thirty or more years of experience in getting dynamic method
dispatch to run efficiently. Techniques such as polymorphic inline
caching, dynamic (re)compilation and others. One of the pioneers of
this work was David Ungar who analyzed Smalltalk performance as his
PhD dissertation, then spearheaded Self which was a language which
turned the dynamic lookup knob up to 11 (it did away with the
distinction between methods and instance variables) which exacerbates
the problems of having to do continuous dynamic lookups and found
techniques to make the language performant. Such techniques formed
the basis of the HotSpot JIT technology in Java.
There is a wealth of literature on efficient implementation of dynamic
languages, particularly in the proceedings of OOPSLA in the mid 1980s
forwards.
To date, the MRI implementations have used rather naive techniques.
JRuby does take advantage of JVM implementation techniques, albeit a
bit less directly than say MagLev which is built on a similarly
sophisticated VM which was engineered for Smalltalk rather than Ruby a
language whose underlying object model more closely maps to Ruby than
does Java.
Now, I'm far from an expert on JVM implementation, but the last time I
looked, it seemed that interfaces were really only used in method
dispatch as a way to provide the equivalent of what Ruby uses symbols
for. In ruby the method invocations
a.foo
a.foo(1)
a.foo("abc")
All resolve to the same method, where in Java these would be different
overloaded methods based on different types and numbers of parameters
(different signatures). So the combination of method name and
parameter type list needs to be mapped to a 'selector' of a method
defined in a particular (super)class or interface. The java bytecodes
to call a method typically involve fetching a 'token' from a class or
interface (which is known because of the type of the variable
'receiving' the call, and then calling a dispatch function with the
receiver, the token, and the argument values. This is very similar to
what happens in Ruby except that instead of a token based on the name
and parameter types, Ruby just uses the symbol form of the method
name.
What happens on the other side of the dispatch function is hidden, but
the effect is for the VM to find the right method implementation and
invoke it.
The traditional C++ implementation of virtual functions uses the
compiler's knowledge of the called object type and the class hierarchy
of that type to find a virtual function table and index that to find a
pointer to the method. This turns out to be very fragile, and is why
large C++ programs have LOTS more make dependencies than does a
typical C program, meaning that small source code changes can require
MANY files to be recompiled to make sure everyone has the right
locations of VFTs and virtual function indexes.
If you're interested in this try googling for "fragile base class
problem." This issue be-deviled those who tried to use C++ to build
"framework-based" OS APIs during the days of C++ fever.
http://talklikeaduck.denhaven2.com/2007/06/15/a-meeting-with-gill-bates *
http://talklikeaduck.denhaven2.com/2009/10/10/oh-the-irony
Another related bit of history is the war between different
semi-static/semi-dynamic "object models" like IBM's SOM vs.
Microsoft's COM *. Although I was playing for the "IBM team" I never
thought much of either to be honest.
http://en.wikipedia.org/wiki/IBM_System_Object_Model
http://en.wikipedia.org/wiki/Component_Object_Model
This approach falls down completely when the type hierarchy can change
at run-time and I'm pretty sure that most JVMs do the actual method
lookup more dynamically and use caching to achieve performance.
* BTW, Tony Williams who is considered as the co-inventor of COM was
IIRC the guy presenting in this meeting, and if he wasn't the
presenter he was in the room.
