Re: [cme-dev] Any body working with CME component APIs?
|
Hi Santhosh,
Your request for a sample makes a lot of sense. I created a new project
called "samples" under the demo folder in the CVS repository. It currently
contains one sample, which sets up a concern space and the runs a query
against it. It is not a tiny example, but a more realistic one based on the
CME AOSD '04 demo, but still small enough to examine easily. It has lots of
comments. The class comment explains how to compile and run the sample.
The query part of the example is short, and is attached below.
Regards, Harold
/**
* Setup and run an example query. The query finds all calls to
"register" methods occurring in the
* OperatorTypes concern set up before.
*/
private void doExampleQuery() {
// All queries are executed in a QueryContext. Create a new
one.
QueryContext context = new QueryContextImpl();
// Indicate that the colleciton to be searched is to be the
entire concern space (_space is a field in the object containing this
method)
context.setInputCollection(_space);
// Set up the query itself, in the Panther query language.
Pattern query = new PantherPatternImpl("in(concern
OperatorTypes) && call(* register(..))");
context.setQuery(query);
// Execute the query.
Searchable result = context.evaluateQuery(new
UninterruptibleMonitor());
// Print the results. This printer knows how to print
collections (Searchables) that contain ConMan elements.
ObjectPrinter op =
ConcernModelPrinter.getDelimitedSearchablePrinter();
op.print("Query results: ", result, 0);
}

Please respond to

Hi,
The tech reports and the user guides are of great help. It would be
great
if we could have a sample code frgment that independently runs a query on
a sample file and prints the result. I understand that there are
classes in test files
that show us how to do it, but is it necessary that we go through
that before starting
on our own..as a begginner?
Thanks and regards
Santhosh

If there is but a thin line seperating a fool and a genius, then I
