Subject [jira] [Updated] (MATH-1041) Add Pair factory method, toString(), Comparator
Date Wed, 16 Oct 2013 08:41:42 GMT

     [ https://issues.apache.org/jira/browse/MATH-1041?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sean Owen updated MATH-1041:
----------------------------

    Description: 
I use Commons Math heavily, and have adopted its Pair class for the cases where I need, well,
a pair of things.

The attached patch adds three small improvements to the Pair class:

- toString() method
- factory method ".create()" to avoid duplicating generic types on instance creation
- a Comparator

Tests are included. I won't feel offended if this is rejected or modified but just wanted
to supply  the suggestion.
