Subject [jira] Commented: (MATH-424) MultiDimensionMismatchException.getWrongDimensions() fails to clone the array
Date Fri, 01 Oct 2010 17:42:32 GMT

    [ https://issues.apache.org/jira/browse/MATH-424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12916967#action_12916967
] 

Sebb commented on MATH-424:
---------------------------

Another way to avoid copying yet still provide read-only access to the array would be to use
an indexed getter.

That would be safe even for "insane" code.

> MultiDimensionMismatchException.getWrongDimensions() returns a pointer to the array,
which allows callers to modify it.
> The constructor takes care to clone the input array, so presumably the getter should
do so too?
> Same applies to getExpectedDimensions()
