Myrna van Lunteren commented on DERBY-4587:
-------------------------------------------
Perhaps add something like *planexporter*/*.xsl to
tools/javadoc/derbydocs_exclusions.ant?
Or perhaps you can just do **/*.xsl (only other .xsl is
tools/ant/xsl/sysinfo_junitreport.xsl).
disclaimer: I'm not certain of the syntax nor have I done any testing.

> I think it would be great to see some work in the area of tools for helping
> with the analysis of complex query execution. Quite frequently, users of
> Derby have trouble comprehending (a) how their query is being translated
> into a query plan by the optimizer, and (b) what the execution-time resource
> usage of the various parts of the query is.
> There are low-level features in Derby which capture this information and
> record it, such as logQueryPlan, and the XPLAIN tables, but there is a lot
> of opportunity for designing higher-level tools which can process the query
> plan and execution statistics information and present it in a more
> comprehensible fashion.
