Examples of com.google.inject.spi.PrivateElements

com.google.inject.spi.PrivateElements
A private collection of elements that are hidden from the enclosing injector or module by default. See {@link com.google.inject.PrivateModule PrivateModule} for details. @author jessewilson@google.com (Jesse Wilson) @since 2.0
