I am trying to analyze a Java heap dump file in ".hprof" format with the help of Eclipse standalone MAT analyzer tool. I am trying to do this programmatically through command line.I want to access the dominator tree that is generated in Eclipse after analyzing a heap dump file. Is there a command line argument or an API that I can use to access this dominator tree from outside Eclipse GUI?
(a) http://wiki.eclipse.org/MemoryAnalyzer/FAQ#How_to_run_on_64bit_VM_while_the_native_SWT_are_32bit (b) https://help.eclipse.org/kepler/index.jsp?topic=%2Forg.eclipse.mat.ui.help%2Fdoc%2Findex.html
After going through the above two resources, I found that I could use the below command line arguments to parse the hprof initially and then generate the leak report in ZIP format:
(i) org.eclipse.mat.api.parse: For parsing the hprof file (ii) org.eclipse.mat.api:suspects: For creating a ZIP file containing the leak suspect report (iii) org.eclipse.mat.api:overview: For creating a ZIP file containing the overview report (iv) org.eclipse.mat.api:top_components: For creating a ZIP file containing the top components report.
But I am not able to find any similar command line argument through which I can access the dominator tree. I am using the below command line to initially parse the hprof file and then generate the leak suspects report:
ParseHeapDump.sh (path to hprof file) org.eclipse.mat.api:suspects
I expect a similar command line argument or an API that can help to access the dominator tree outside Eclipse GUI.
