      public class AttributeList
      extends ArrayList<Object>

  Represents a list of values for attributes of an MBean. See the `getAttributes` and `setAttributes` methods of `MBeanServer` and `MBeanServerConnection`.

  For compatibility reasons, it is possible, though highly discouraged, to add objects to an `AttributeList` that are not instances of `Attribute`. However, an `AttributeList` can be made type-safe, which means that an attempt to add an object that is not an `Attribute` will produce an `IllegalArgumentException`. An `AttributeList` becomes type-safe when the method `asList()` is called on it.

- - ### Constructor Detail

    - #### AttributeList

          public AttributeList()

      Constructs an empty `AttributeList`.

    - #### AttributeList

          public AttributeList(int initialCapacity)

      Constructs an empty `AttributeList` with the initial capacity specified.
      Parameters:
        `initialCapacity` - the initial capacity of the `AttributeList`, as specified by `ArrayList.ArrayList(int)`.

    - #### AttributeList

          public AttributeList(AttributeList list)

      Constructs an `AttributeList` containing the elements of the `AttributeList` specified, in the order in which they are returned by the `AttributeList`'s iterator. The `AttributeList` instance has an initial capacity of 110% of the size of the `AttributeList` specified.
      Parameters:
        `list` - the `AttributeList` that defines the initial contents of the new `AttributeList`.
      See Also:
        `ArrayList.ArrayList(java.util.Collection)`

    - #### AttributeList

          public AttributeList(List<Attribute> list)

      Constructs an `AttributeList` containing the elements of the `List` specified, in the order in which they are returned by the `List`'s iterator.
      Parameters:
        `list` - the `List` that defines the initial contents of the new `AttributeList`.
      Throws:
        `IllegalArgumentException` - if the `list` parameter is `null` or if the `list` parameter contains any non-Attribute objects.

        1.6

        `ArrayList.ArrayList(java.util.Collection)`

  - ### Method Detail

    - #### asList

          public List<Attribute> asList()

      Return a view of this list as a `List<Attribute>`. Changes to the returned value are reflected by changes to the original `AttributeList` and vice versa.
      Returns:
        a `List<Attribute>` whose contents reflect the contents of this `AttributeList`.

        If this method has ever been called on a given `AttributeList` instance, a subsequent attempt to add an object to that instance which is not an `Attribute` will fail with a `IllegalArgumentException`. For compatibility reasons, an `AttributeList` on which this method has never been called does allow objects other than `Attribute`s to be added.

      Throws:
        `IllegalArgumentException` - if this `AttributeList` contains an element that is not an `Attribute`.
      Since:
        1.6

    - #### add

          public void add(Attribute object)

      Adds the `Attribute` specified as the last element of the list.
      Parameters:
        `object` - The attribute to be added.

    - #### add

          public void add(int index,
                 Attribute object)

      Inserts the attribute specified as an element at the position specified. Elements with an index greater than or equal to the current position are shifted up. If the index is out of range (index < 0 || index > size()) a RuntimeOperationsException should be raised, wrapping the java.lang.IndexOutOfBoundsException thrown.
      Parameters:
        `object` - The `Attribute` object to be inserted.
        `index` - The position in the list where the new `Attribute` object is to be inserted.

    - #### set

          public void set(int index,
                 Attribute object)

      Sets the element at the position specified to be the attribute specified. The previous element at that position is discarded. If the index is out of range (index < 0 || index > size() a RuntimeOperationsException should be raised, wrapping the java.lang.IndexOutOfBoundsException thrown.
      Parameters:
        `object` - The value to which the attribute element should be set.
        `index` - The position specified.

    - #### addAll

          public boolean addAll(AttributeList list)

      Appends all the elements in the `AttributeList` specified to the end of the list, in the order in which they are returned by the Iterator of the `AttributeList` specified.
      Parameters:
        `list` - Elements to be inserted into the list.
      Returns:
        true if this list changed as a result of the call.
      See Also:

      Inserts all of the elements in the `AttributeList` specified into this list, starting at the specified position, in the order in which they are returned by the Iterator of the `AttributeList` specified. If the index is out of range (index < 0 || index > size() a RuntimeOperationsException should be raised, wrapping the java.lang.IndexOutOfBoundsException thrown.
      Parameters:
        `list` - Elements to be inserted into the list.
        `index` - Position at which to insert the first element from the `AttributeList` specified.
      Returns:
        true if this list changed as a result of the call.
      See Also:
        `ArrayList.addAll(int, java.util.Collection)`
