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.

AttributeList
public AttributeList()Constructs an emptyAttributeList
. -
AttributeList
public AttributeList(int initialCapacity)Constructs an emptyAttributeList
with the initial capacity specified.- Parameters:
initialCapacity
- the initial capacity of theAttributeList
, as specified byArrayList(int)
.
-
AttributeList
Constructs anAttributeList
containing the elements of theAttributeList
specified, in the order in which they are returned by theAttributeList
's iterator. TheAttributeList
instance has an initial capacity of 110% of the size of theAttributeList
specified.- Parameters:
list
- theAttributeList
that defines the initial contents of the newAttributeList
.- See Also:
ArrayList(java.util.Collection)
-
AttributeList
Constructs anAttributeList
containing the elements of theList
specified, in the order in which they are returned by theList
'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

ArrayList(java.util.Collection)

Method Details
-
asList
Return a view of this list as aList<Attribute>
. Changes to the returned value are reflected by changes to the originalAttributeList
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
Adds theAttribute
specified as the last element of the list.- Parameters:
object
- The attribute to be added.
-
add
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
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
Appends all the elements in theAttributeList
specified to the end of the list, in the order in which they are returned by the Iterator of theAttributeList
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
Inserts all of the elements in theAttributeList
specified into this list, starting at the specified position, in the order in which they are returned by the Iterator of theAttributeList
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
Appends the specified element to the end of this list.- Specified by:
add
in interfaceCollection<Object>
- Specified by:
add
in interfaceList<Object>
- Overrides:
add
in classArrayList<Object>
- 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
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). -
addAll
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.)- Specified by:

- Overrides:
addAll
in classArrayList<Object>
- Parameters:
c
- collection containing elements to be added to this list- Returns:
true
if this list changed as a result of the call- Throws:
IllegalArgumentException
- if thisAttributeList
is type-safe andc
contains an element that is not anAttribute
.- See Also:
AbstractCollection.add(Object)
-
addAll
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).

addAll
in interfaceList<Object>
- Overrides:
addAll
in classArrayList<Object>
- Parameters:
index

- collection containing elements to be added to this list- Returns:
