Viagra Affect A Female

Viagra affect a female In my few days of being a developer, viagra affect a female I’ve heard and seen lots of talk about Singletons.  Things like

Viagra affect a female Singletons are teh suck.  Don’t use them.  EVAR.

Viagra affect a female to

Viagra affect a female Singleton’s saved my life and marriage!

Viagra affect a female In fact, viagra affect a female I might’ve been the person that said both of these… gasp!

Viagra affect a female I never like to speak in absolutes, viagra affect a female so I’ll say it this way (see what I did there?)… if you’re striving to implement a singleton, viagra affect a female you’re probably wrong.  For all you guys that are right, viagra affect a female I guess you’re right, viagra affect a female and you can leave now, viagra affect a female I guess.  This might help you out.

Viagra affect a female I was reading a blog from Mr. Viagra affect a female Dependency where he was talking about statics and basically what amounts to global state, viagra affect a female and how thatultimate-geeks-multi-tool-hammer binds you into globally available, viagra affect a female global data, viagra affect a female which usually (always?) turns into anarchy.

Viagra affect a female How do we always get ourselves into this mess if we know it’s bad in the first place?  Well, viagra affect a female some of us (those who are now zombocomming, viagra affect a female from above) don’t know it’s bad in the first place, viagra affect a female and the rest of us probably do it because it’s easy to implement, viagra affect a female and we understand it.  Long story short, viagra affect a female we can do the singleton implementation in our sleep, viagra affect a female so we pull out the singleton hammer, viagra affect a female and smack the nail.  It always goes in a little sideways, viagra affect a female but at least it goes in.

Viagra affect a female Maybe we should be using a different hammer?

Viagra affect a female What I’d like to do now, viagra affect a female is propose to split singleton in two.  I think there are two distinct responsibilities that the current thought of ‘singleton’ introduces. Viagra affect a female It:

  • Manages Session Scoping/Lifecycle/Lifestyle (albeit, viagra affect a female poorly, viagra affect a female only one strategy is available)
  • Disables the ability to create more

Viagra affect a female When I talk about this out loud, viagra affect a female I call the two approaches the singleton implementation pattern, viagra affect a female and singleton lifecycle.

Viagra affect a female What I am a fan of, viagra affect a female is the singleton lifecycle.  You create one of those objects, viagra affect a female and use it throughout the application.  You don’t get messy and allow global access to it all over the place (which necessarily happens when you have global state).  You intentionally inject it to collaborators, viagra affect a female and  intentionally don’t inject it to non-collaborators (don’t just hand this guy out willy-nilly, viagra affect a female he’s important).

Viagra affect a female So naturally, viagra affect a female the naysayers ask/demand:

Viagra affect a female How do you manage that there is a public constructor on this class!?  Dev’s are going to be new’ing this thing up all over the place!

Viagra affect a female I say:

Viagra affect a female False.  Use a DI tool and let it manage it for you.  Or establish a convention with your team, viagra affect a female and enforce it through social contracts. Viagra affect a female

Viagra affect a female Both of these approaches allow your scope lifecycle turn into whatever you want at any time, viagra affect a female in case you decide global isn’t what you really want.  It can be application session scoped, viagra affect a female or some other scope, viagra affect a female test scoped, viagra affect a female or whatever you want… incredibly flexible.

Viagra affect a female If you go with the DI tool approach, viagra affect a female instead of tying yourself to a particular scope, viagra affect a female you can now have any scope you want, viagra affect a female by changing a configuration parameter.  Delaying decisions until the latest responsible moment… seems like I’ve heard that one before.
