Subject: Remove comparison operators from PointerMatrixBase and associated infrastructure...
X-Git-Tag: v8.2.0-rc1~823
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7cfb13470055cddc1f0a258065c6512f991ea6c0;p=dealii.git
Remove comparison operators from PointerMatrixBase and associated infrastructure. This wasn't used anywhere and was likely not working in at least some circumstances.

+ - Removed: Class PointerMatrixBase (and, consequently, the various
+ classes derived from it) had comparison operators that were intended to
+ work generically for any kind of derived class. However, the implementation
+ used a scheme that was not robust enough to handle the various situations
+ that derived classes implemented and, consequently, was not always correct.
+ These operators were not previously used inside the library and, likely,
+ were not widely used in applications either. They have now been removed.

- Changed: The various classes generating graphical output, such
as DataOut or DataOutStack, are all derived from a common interface
class DataOutInterface which, in turn was derived from DataOutBase
