  - ### Enum Constant Summary

    Enum Constants
    Enum Constant and Description
    `PROTOTYPE` One instance per injection.
    `REQUEST` One instance per request.
    `SESSION` One instance per session.
    `SINGLETON` One instance per container.
    `THREAD` One instance per thread.

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `static Scope` | `valueOf(String name)` Returns the enum constant of this type with the specified name.
    `static Scope[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

      `clone, compareTo, equals, finalize, getDeclaringClass, hashCode, name, ordinal, toString, valueOf`

    - ### Methods inherited from class java.lang.Object

      `getClass, notify, notifyAll, wait, wait, wait`

- - ### Enum Constant Detail

    - #### PROTOTYPE

          public static final Scope PROTOTYPE

      One instance per injection.

    - #### SINGLETON

          public static final Scope SINGLETON

      One instance per container.

    - #### THREAD

          public static final Scope THREAD

      One instance per thread.

      Note: if a thread local object strongly references its `Container`, neither the `Container` nor the object will be eligible for garbage collection, i.e. memory leak.

    - #### REQUEST

          public static final Scope REQUEST

      One instance per request.

    - #### SESSION

          public static final Scope SESSION

      One instance per session.

    - #### WIZARD

          public static final Scope WIZARD

      One instance per wizard.

  - ### Method Detail

    - #### values

          public static Scope[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (Scope c : Scope.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static Scope valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null
