Field Detail

print_synchro

public static final Object print_synchro

Global lock to prevent interleaving of progress display messages.

exit_if_no_steps_after_milliseconds

private static int exit_if_no_steps_after_milliseconds

Give up after this many milliseconds, if the generator has not taken a step. That is, if it has not attempted to generate a new test sequence.

outputMode

private final ProgressDisplay.Mode outputMode

The output mode.

generator

private AbstractGenerator generator

The test generator.

shouldStop

public boolean shouldStop

Clients should set this variable instead of calling Thread.stop(), which is deprecated. Typically a client calls "display()" before setting this.

lastStepTime

private long lastStepTime

When the most recent step completed.

lastNumSteps

private long lastNumSteps

The step number of the most recent step.
