com.google.common.util.concurrent.FakeTimeLimiter Maven / Gradle / Ivy
Go to download
This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up
with different versions on classes on the class path).

/**
* A TimeLimiter implementation which actually does not attempt to limit time at all. This may be
* desirable to use in some unit tests. More importantly, attempting to debug a call which is
* time-limited would be extremely annoying, so this gives you a time-limiter you can easily swap in
* for your real time-limiter while you're debugging.
