Example 7 with PrivateBinder

the class CheckedProviderMethod method configure.

    SecondaryBinder<?, ?> sbinder = ThrowingProviderBinder.create(binder).bind(checkedProvider, key.getTypeLiteral());
    if (key.getAnnotation() != null) {

    }
    ScopedBindingBuilder sbbuilder = sbinder.toProviderMethod(this);
    if (scopeAnnotation != null) {
        sbbuilder.in(scopeAnnotation);
    }
    if (exposed) {
        // the cast is safe 'cause the only binder we have implements PrivateBinder. If there's a
        // misplaced @Exposed, calling this will add an error to the binder's error queue
        ((PrivateBinder) binder).expose(sbinder.getKey());
    }
    CheckedProvideUtils.validateExceptions(binder, exceptionTypes, sbinder.getExceptionTypes(), checkedProvider);
