Method Detail

startDDRInteractiveSession

public void startDDRInteractiveSession(Image image,
                                       PrintStream out)

Starts a DDR interactive session using the loaded image. If the core file is not DDR enabled this is recorded and future pling commands will not be available. In order to get access to the DDR classes it uses the Image classloader which, if the core file is DDR enabled, can see the required classes.

Parameters:

image - Image created from the core file
