Jargon in lede
I find the lede of this article to be vague and esoteric to the point of being meaningless. It is composed almost entirely of words that can have a dozen different meanings in different contexts, such as "dependency", "external interface", and "software component".
Fowler's own article has a much clearer single-sentence description of the topic:
The basic idea of the Dependency Injection is to have a separate object, an assembler, that populates a field in the lister class with an appropriate implementation for the finder interface, resulting in a dependency diagram along the lines of Figure 2.
To me, this description (aside from the overly specific example classes "lister" and "finder") is a much clearer one-sentence introduction for those uninitiated in the latest and greatest in software engineering pontification. Can we base our lede on this instead? --Doradus (talk) 02:20, 18 January 2010 (UTC)
- So you don't think that "object", "assembler", "field" and "lister class" are jargon? The purpose of the first sentence is not to provide a precise definition (which can be done later) but introducing a feeling of the subject ("an accessible overview") to the general reader - that including people without knowledge of OOP.
- I have no problem with the words being vague (disclaimer: I wrote the current version of the lead paragraph), among other reasons because it allows for *different * implementations of DI other than the one described by Fowler (which is not necessarily the only one) - but mainly because "dependency" and "software component" are quite self-explaining even for non programmers.
- If you find Fowler's definition clearer, you can add it later in the lead section for the benefit of readers who already know OOP. Diego (talk) 09:52, 18 January 2010 (UTC)
