Class AttributeList

java.lang.Object
  java.util.AbstractCollection<E>
      java.util.AbstractList<E>
          java.util.ArrayList<Object>
              javax.management.AttributeList

All Implemented Interfaces:: Serializable, Cloneable, Iterable<Object>, Collection<Object>, List<Object>, RandomAccess

public class AttributeList
extends ArrayList<Object>
extends ArrayList<Object>

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.

Since:: 1.5

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.
Since:: 1.6
See Also:: 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 Attributes 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:: ArrayList.addAll(java.util.Collection)

addAll

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:: 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)
