Using Generics to Manipulate Enumerated Types

I’d like to present a short class written by my colleague at work. Why? Because I just love how it uses the generics syntax to simplify some operations on enumerated types.

Like me, he hated the hoops one must jump through to convert an instance of an enumerated type to a string, to check if an integer value that was read from some storage contains a valid integer representation of some enumerated value and to enumerate (no pun intended) over such a type. Unlike me, he did something about that and wrote a Spring-inspired Range<T>.

Branch mispredict 5.0
L2 cache reference 7.0
Mutex lock/unlock 100.0
Main memory reference 100.0
Compress 1K bytes with Zippy 10,000.0
Send 2K bytes over 1 Gbps network 20,000.0
Read 1 MB sequentially from memory 250,000.0
Round trip within same datacenter 500,000.0
Rusty disk seek 10,000,000.0
Read 1 MB sequentially from network 10,000,000.0

From always excellent kellabyte.

Embarcadero Academy: The Power of XE3

Next Wednesday (March 13th) we have organized a presentation for all users that are afraid to upgrade and are staying (for example) with Delphi 7. In “The Power of XE3” session I’ll go through all* new features added to the Delphi and C++ Builder since Delphi 7 days. We’ll discuss language changes, platform changes, framework changes, additions to the VCL, RTL, database layer …

Register here.

* As much as humanly possible. There are simply too many to cover them all.
