view src/main/gov/nasa/jpf/vm/NamedFields.java @ 21:caa0924e093d
reshuffled Event hierarchy, introducing SystemEvent, with CheckEvent and
ControlEvent being subclasses of SystemEvent
added Loggable.setLogLevel
changed old UserHeuristic to use a Verify.heuristicValue instead of a
hardwired "Main" class with hardwired fields (which was just an outdated
leftover). Call Verify.setHeuristicValue() to control state priorities from the
SUT.
This also fixes the bug that UserHeuristic was not properly checking for
"Main" resolution.
