Class Overview

Represents a list of values for attributes of an MBean. The methods used for the insertion of Attribute objects in the AttributeList overrides the corresponding methods in the superclass ArrayList. This is needed in order to insure that the objects contained in the AttributeList are only Attribute objects. This avoids getting an exception when retrieving elements from the AttributeList.

Public Constructors

public AttributeList ()

Constructs an empty 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(int).

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.

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.

Public Methods

public void add (int index, Object element)

Inserts the specified element at the specified position in this list. Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

Parameters
index index at which the specified element is to be inserted
element element to be inserted

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
index The position in the list where the new Attribute object is to be inserted.
object The Attribute object to be inserted.

public void add (Attribute object)

Adds the Attribute specified as the last element of the list.

Parameters
object The attribute to be added.

public boolean add (Object o)

Appends the specified element to the end of this list.

Parameters
o element to be appended to this list
Returns
  • true (as specified by add(E))

public boolean addAll (int index, AttributeList list)

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
index Position at which to insert the first element from the AttributeList specified.
list Elements to be inserted into the list.
Returns
  • true if this list changed as a result of the call.

public boolean addAll (int index, Collection<?> c)

Inserts all of the elements in the specified collection into this list, starting at the specified position. Shifts the element currently at that position (if any) and any subsequent elements to the right (increases their indices). The new elements will appear in the list in the order that they are returned by the specified collection's iterator.

Parameters
index index at which to insert the first element from the specified collection
c collection containing elements to be added to this list
Returns
  • true if this list changed as a result of the call

public boolean addAll (Collection<?> c)

Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's Iterator. The behavior of this operation is undefined if the specified collection is modified while the operation is in progress. (This implies that the behavior of this call is undefined if the specified collection is this list, and this list is nonempty.)

Parameters
c collection containing elements to be added to this list
Returns
  • true if this list changed as a result of the call

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.

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 Attributes to be added.

Throws
IllegalArgumentException if this AttributeList contains an element that is not an Attribute.

public Object set (int index, Object element)

Replaces the element at the specified position in this list with the specified element.

Parameters
index index of the element to replace
element element to be stored at the specified position
Returns
  • the element previously at the specified position

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
index The position specified.
object The value to which the attribute element should be set.
