Return list of available topics in rosjava?

edit

Hello, I am trying to make a Swing GUI where I can subscribe to different available topics at run-time. The idea would be that you could right click somewhere on the GUI, and a list of available topics would pop up. You could then select a topic and it would automatically create a widget that would subscribe to the said topic and display relevant information.

Is there a way to list all of the topics running on a core from within a rosjava program? Ideally, it would act in a manner similar to calling rostopic list, but allow the program running to read in the names of the topics. Any help would be greatly appreciated.

Thank you,
