public void run(org.eclipse.jface.action.IAction action)
Traverse all the ICompilationUnit's methods using an AST, calculating the position of each, and adding System.out.println for each method parameter.

Specified by:

setActiveEditor

public void setActiveEditor(org.eclipse.jface.action.IAction action,
                            org.eclipse.ui.IEditorPart targetEditor)
Instances of IEditorActionDelegate are shared among editors of the same type; this method notifies the action that it now "works" for another editor. This determines the context for availability of this action and the target of the run method.

Specified by:
setActiveEditor in interface org.eclipse.ui.IEditorActionDelegate
