No, C++ Fast Delegates aren't really trading algorithms, but they do help make trading algorithms fast.
In the C# world, the C# language has the built-in capacity to store multiple
object/method pointers and call them in response to some sort of activity. This is
generally referred to the Observer Pattern of event based programming. In C#, the structure is
called a Delegate.
C++ does not provide a native Delegate structure. Don Clugston wrote an article called
Member Function
Pointers and the Fastest Possible C++ Delegates. I've used this method successfully
with Microsoft Visual Studio 2005.
Don's implementation is unable to do multicast delegates. Sergey Ryazanov wrote an
article called The
Impossibly Fast C++ Delegates that supposedly is more C++ compliant and has a multicast
capability.
JaeWook Choi took the work one step farther and implemented a multicast delegate that is
a drop in replacement for the Boost C++
Libraries. Boost is a collection of free peer-reviewd portable C++ source libraries.
JaeWook's library is faster than Boost, but slower than Don's library. But JaeWook's
library is mulitcast and does offer up additional functionality. Timings and feature sets
can be reviewed in his article called Fast C++ Delegate:
Boost.Function 'drop-in' replacement and multicast.
