Subject [jira] Commented: (LANG-588) Create a basic Pair<L, R> class
Date Wed, 10 Feb 2010 20:33:27 GMT

    [ https://issues.apache.org/jira/browse/LANG-588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12832181#action_12832181
] 

Matt Benson commented on LANG-588:
----------------------------------

I understand that, but apparently what I am not conveying is my assumption that the type parameters
would carry a mnemonic correlation with the class members that carry the constituent parts
of the Pair.  I would thus expect, perhaps:

left/right->L/R
a/b->A/B
x/y->X/Y
thing1/thing2->T1/T2

...and my more facetious suggestions are perhaps too ridiculous for this exercise.

> [lang] is the perfect place to provide a basic typed Pair class.  I have written such
a class for my employer (who hasn't?) but can/will rewrite blind to avoid IP issues.  I think
it's also nice to go ahead and extend this to MatchedPair<T> extends Pair<T, T>
as well.
