Israfil Micro-Container
------
Christian Edward Gruber
------
May 2, 2007
Overview
The micro-container is an extremely lightweight IoC container supporting
dependency injection. It is built with the principles in mind that
spawned {{{http://www.picocontainer.org/} pico-container}} but with the
explicit constraints to which J2ME applications centered around the
CLDC 1.1 are bound. This includes a complete absence of any constructor
or method lookup (reflection) or dynamic proxy support.
Like pico-container, Israfil's micro-container only handles the
registration and vending of components, not additional services such as
persistence, and the like.
Isn't Micro bigger than Pico?
Yes, but micro-container wasn't as taken, and israfil-micro is a placeholder
for any further frameworks that might be developed in the J2ME footprint.
I briefly considered femto-container, but it was too obscure even for me.
Can I use this in commercial or other software?
Yes. The micro-container, as with all Israfil Micro and Foundation libraries
are licensed under the terms of the BSD license, which provides you with a
license to distribute with or without modification, and to prepare derivative
works, with the sole exception that you retain the notice (specific terms
are available in the license page linked from the menu.) The short answer
is yes, go for it, it won't cost you a penny, and you won't be obliged to
show anyone your code.
How do I use it?
I recommend looking at pico-container's site for really good theoretical
presentations of this kind of software. Tapestry5 also contains an ioc
framework par-excellence, and it has some ok docs. Some specific usage
documentation for this framework (around staging the container and getting
things set up in a practical application) are available in the usage page
linked from the menu.
