Examples to help discussions
Hi,
In order to ground our discussions I'd like for there to be examples
for the points we are discussing. I've constructed an example that shows
how you would print out the contents of a JVM heap using the API. That
way we have a small piece of code that demonstrates an application of
the API in its full horror.
I've put it on the Wiki at
http://cwiki.apache.org/confluence/display/KATO/Object+Fields+example
And in the repository under
https://svn.apache.org/repos/asf/incubator/kato/trunk/org.apache.kato.example/src/org/apache/kato/example/
The example has been put in two places as not everyone will be able to
look in the repository.
Please ask me questions about any of it. I'd like to update the example
as the discussions continue, and I'd think it might be useful to use
some snippets from the example to use as examples of how things are done
just now, and what they would look like if the API was different.
The sample just touches JavaObject, JavaClass, JavaHeap and JavaField -
I wouldn't mind writing more examples if people would like them.
Regards,
Stuart
P.S. Here is some output from an actual run on the example:
