Field Detail

optimizationPlans

private final Vector<OptimizationPlanElement[]> optimizationPlans

optimizationPlanLocks

private final Vector<Boolean> optimizationPlanLocks

options

private final Vector<OptOptions> options

masterOptions

private final OptOptions masterOptions

excludePattern

private String excludePattern
If excludePattern is null, all methods are opt-compiled (or attempted). Otherwise, methods that match the pattern are not opt-compiled. In any case, the class OptSaveVolatile is always opt-compiled.
