[jira] [Commented] (MATH-894) Cleanup of "ResizableDoubleArray" ("o.a.c.m.util")

    [ https://issues.apache.org/jira/browse/MATH-894?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13497051#comment-13497051 ] 

Gilles commented on MATH-894:
-----------------------------

Shall we make the "expansionFactor", "contractionCriteria"[1] and "expansionMode" fields "final" (and hence deprecate the corresponding setters)? 
I don't really see the usefulness of being able to fiddle with these values during an object's lifetime. I'd rather add copy constructors that would allow to set those parameters to values different from the copied instance.

[1] Shouldn't this variable be named "contractionCriterion"?

> Method "addElement" should not call "contract()", as it will almost always make the storage array shrink on the first call since it will be considered "too big" (for just storing one element).
> See discussion about this change in MATH-757.
> Miscellaneous code modifications are also proposed in order to improve encapsulation.
