GSOC ReportBuilder Weekly Update

[Adam Seskunas]

This week I began work on subclassing ORptExport to create a second
export filter. The goal is to modify the export path of a report so that
one filter can be used for saving a report and one filter can be used to
execute a report. This allows us to maintain backwards compatibility with
existing reports while allowing us to bypass the Pentaho Report engine
when executing a report

With the help of my mentor Michael I was able to get the subclass
implemented and I have begun work on reducing the code redundancy
between the two classes. The goal is to be able to wrap the new
parts of the filter implementation in function calls from the base class.
This will make maintaining the code easier and allow for easier debugging.

With this in mind I have submitted a patch to Gerrit that splits up the
ORptExport::exportContainer function into four logical chunks.

https://gerrit.libreoffice.org/c/core/+/188189

As I continue working on the implementation of the new export filter I will
continue to go over the functions in ORptExport to see if they can be
broken
down into smaller pieces. This will hopefully aid in my efforts to reduce
any
code redundancies and will make maintaining and debugging the code in
ORptExport easier moving forward.

After the new export filter is finished I will change the current filter
call so that
it executes the appropriate filter depending on how the filter is called.
My
mentor Michael was kind enough to do some work to make this easier, the
patches can be found here.

https://gerrit.libreoffice.org/c/core/+/187948
https://gerrit.libreoffice.org/c/core/+/187914

After finishing the filter(s) implementation I will begin to work on
implementing
Grouping functionality in C++.

Thanks for reading, have a good week!
