Class FakeConstantBoolean
java.lang.Object
dev.pfaff.altargui.util.FakeConstantBoolean
A wrapper for a boolean value that is stored and accessed via a
MutableCallSite
. The JVM should be able to
optimize uses of the value more than if it were simply a non-final field.
From my testing, it appears that the Hotspot JVM has more aggressive speculative optimization of CallSite
s
than it does non-final fields. That knowledge led to the creation of this wrapper class. Note that this technique
will only be effective if the Hotspot JVM is run with -XX:+TrustFinalNonStaticFields
.
