Getting Started
To begin an analysis with JRipples, press “Start
analysis” in the main JRipples menu.
This will open a configuration dialog, where a
project and a main class for the analysis should be selected. After this,
simply press the “Finish” button.
After the “Finish” button is pressed,
JRipples will parse the selected project and open a default JRipples view containing
a list of the parsed classes.
At this point, JRipples is ready for Concept Location activity of Incremental Change. To switch to another activity, simply press IA (Impact Analysis) or CP (Change Propagation) button, as highlighted by a green frame in the picture above.
To view the source code of a component selected in JRipples, double click on the name of this component in the view.
- To change the mark of a component and to apply a propagation rule, right click on the component and select one of the new marks available from the context menu. Usually, a change in the mark of a component will also change marks of the neighbors of this component.
- Please note that the set of the possible new marks for a
component depends on the current state of the component as determined by
the Propagation rules. For
example, the mark of the
Next component can be changed to any of 
Impacted, 
Propagating or 
Unchanged; on the other hand, there are no new marks available
for the
Blank
components. For experimental purposes, this restriction is disabled in incremental
change modules that have “Relaxed” in their names.
To undo or redo the last action, press undo or redo button either on the view’s toolbar, in right-click context menu, or in Eclipse’s edit menu.
To save or restore current state of JRipples analysis, use “Save” and “Load” buttons in JRipples top menu.
