public interface MultiverseConstants
An interface containing global constants. It is a final instead of something mutable so
that the JIT can completely remove code if some condition has not been met. The advantage is that you don't have to
pay to price for adding some kind of check, if it isn't used. The problem is that the scope is all classes loaded by
some classloader, share the same configuration. So one STM implementation with sanity checks enabled and the other
not, is not possible.
It is an interface so that is can be 'implemented' for easier access.

SHAKE_BUGS
static final boolean SHAKE_BUGSIndicates of the bugshaker is enabled (for more information see theBugshaker
. If disabled, no overhead because it can be removed by the JIT. -
TRACING_ENABLED
static final boolean TRACING_ENABLEDIndicates if tracing (so seeing what is going on inside transactions) is enabled. Normally this causes overhead of not used, with this flag the complete tracing logic can be removed by the JIT if disabled). -
SPIN_YIELD
static final int SPIN_YIELDIndicates how often the system should yield when it is spinning. When a thread is yielded, it gives the opportunity to another thread to make progress. -
