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 theAttributeList
, as specified byArrayList(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
- theAttributeList
that defines the initial contents of the newAttributeList
. - See Also:
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
- theList
that defines the initial contents of the newAttributeList
. - Throws:
-
IllegalArgumentException
- if thelist
parameter isnull
or if thelist
parameter contains any non-Attribute objects. - Since:
- 1.6
- See Also:
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 thisAttributeList
.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 anAttribute
will fail with anIllegalArgumentException
. For compatibility reasons, anAttributeList
on which this method has never been called does allow objects other thanAttribute
s to be added. - Throws:
-
IllegalArgumentException
- if thisAttributeList
contains an element that is not anAttribute
. - 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
- TheAttribute
object to be inserted. -
index
- The position in the list where the newAttribute
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 theAttributeList
specified. - Returns:
- true if this list changed as a result of the call.
- See Also:
ArrayList.addAll(int, java.util.Collection)
add
public boolean add(Object element)
Appends the specified element to the end of this list.
- Specified by:

- Parameters:
-
element
- element to be appended to this list - Returns:
-
true
(as specified byCollection.add(E)
) - Throws:
-
IllegalArgumentException
- if thisAttributeList
is type-safe andelement
is not anAttribute
.
add
public void add(int index, Object element)

is not anAttribute
.
addAll
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.)
