We need to understand time complexity of each of the modules. Thus we
are looking for the time spent in each module. A clear understanding of
the control flow when a query evaluation is fired will help us in
evaluation time in each module.
There is a lot more to working with SPARQL and evaluating a query than
just executing it.
OpExecutor is the main class to drive execution.

First of all, sorry for the use "URGENT"
Now, when we open source-code of Apache-Jena (The source
distribution,
which includes the source for Fuseki and all modules in the release
jena-3.0.1-source-release.zip (MD5, PGP
<https://jena.apache.org/download/index.cgi> ) we got many files
like
jena-base, jena-arq, apache-jean, jena-csv and many more.
Now I have some rdf file and a arq query file, I wanted to run
the query
over the rdf. I ran it and got some result. Now when I open
/home/neo/jena-3.0.1/jena-arq/src/main/java/org/apache, I got Query
folder. There are so many files here, I am not getting how the
files are
related.
I'm confused as to why you need the source code and not use the
binaries and public APIs as per the documentation.
Another problem, suppose, my query is
SELECT ?x ?y
{ :x :p ?x }
which files are involved in execution of this query, means deciding
whether query is SELECT or not, where is result get stored?
The "Query" tell you which kind of query it is.
As to the execution - lots of files are involved internally - but
what are you trying to find out by looking at them?

Hello everyone,
I want to know the modules involved in query execution.
Use all of them - use maven and depend on apache-jena-libs
http://jena.apache.org/download/maven.html
thenn you won't miss recursive dependencies.
Suppose I want to
insert my own module in Apache-Jena for Query over some
rdf-graph. What
should I do ?
What are you trying to do? That description is not clear as
to what
you are trying to achieve.
