abstract List<DependencyAndSource> |
ProvisionListener.ProvisionInvocation.getDependencyChain()
Deprecated.
This method is planned for removal in Guice 4.4. Some use cases can be replaced
by inferring the current chain via ThreadLocals in the listener, other use cases can use
the static dependency graph. For example,
bindListener(Matchers.any(), new MyListener());
...
private static final class MyListener implements ProvisionListener {
private final ThreadLocal<ArrayDeque<Binding<?>>> bindingStack =
new ThreadLocal<ArrayDeque<Binding<?>>>() {
{@literal @}Override protected ArrayDeque<Binding<?>> initialValue() {
return new ArrayDeque<>();
}
};
{@literal @}Override public <T> void onProvision(ProvisionInvocation<T> invocation) {
bindingStack.get().push(invocation.getBinding());
try {
invocation.provision();
} finally {
bindingStack.get().pop();
}
// Inspect the binding stack...
}
}
In this example the bindingStack thread local will contain a data structure that is very
similar to the data returned by this list. The main differences are that linked keys are
not in the stack, but such edges do exist in the static dependency graph (inspectable via
HasDependencies.getDependencies()), so you could infer some of the missing edges..
