Class StaticSetter

java.lang.Object

net.amygdalum.xrayinterface.StaticSetter

All Implemented Interfaces:

MethodInvocationHandler

public class StaticSetter
extends Object
implements MethodInvocationHandler

Wraps a static field with modification (setter) access. unfortunately some java compiler do inline literal constants. This setter may change the constant, but does not change inlined literals, resulting in strange effects. better avoid setting static final variables or make sure, that they cannot be inlined (e.g. by making its value a trivial functional expression)
