Method Detail


T get()
Provides a fully-constructed and injected instance of T.

java.lang.RuntimeException - if the injector encounters an error while providing an instance. For example, if an injectable member on T throws an exception, the injector may wrap the exception and throw it to the caller of get(). Callers should not try to handle such exceptions as the behavior may vary across injector implementations and even different configurations of the same injector.
