    Method
    Description
    <T> T
    newInstance(Class<T> type)

    <T> T
    newInstance(Class<T> type, boolean postProcessBean)
    Instantiates a new instance of the given type; possibly injecting values into the object in the process (bean post processing if enabled)
    <T> T
    newInstance(Class<T> type, String factoryMethod)
    Instantiates a new instance of the given type by using the factory method (this will not perform bean post processing)
    boolean
    supportsAutoWiring()
    Whether the injector supports creating new instances using auto-wiring.

    • newInstance

      <T> T newInstance(Class<T> type, String factoryMethod)
      Instantiates a new instance of the given type by using the factory method (this will not perform bean post processing)
      Parameters:

    • newInstance

      <T> T newInstance(Class<T> type, boolean postProcessBean)
      Instantiates a new instance of the given type; possibly injecting values into the object in the process (bean post processing if enabled)
      Parameters:
      type - the type of object to create
      postProcessBean - whether to post process the bean
      Returns:
      a newly created instance

    • supportsAutoWiring

      boolean supportsAutoWiring()
      Whether the injector supports creating new instances using auto-wiring. If this is possible then bean instances is attempt first to be created this way and if not, then the bean can only be created if there is a public no-arg constructor.
