public class AttributeList extends ArrayList<Object>
Represents a list of values for attributes of an MBean. See the
getAttributesandsetAttributesmethods ofMBeanServerandMBeanServerConnection.For compatibility reasons, it is possible, though highly discouraged, to add objects to an
AttributeListthat are not instances ofAttribute. However, anAttributeListcan be made type-safe, which means that an attempt to add an object that is not anAttributewill produce anIllegalArgumentException. AnAttributeListbecomes type-safe when the methodasList()is called on it.- Since:

Constructor Detail

AttributeList
public AttributeList()
Constructs an emptyAttributeList.
-
AttributeList
public AttributeList(int initialCapacity)
Constructs an emptyAttributeListwith the initial capacity specified.- Parameters:
initialCapacity- the initial capacity of theAttributeList, as specified byArrayList(int).
-
AttributeList
public AttributeList(AttributeList list)
Constructs anAttributeListcontaining the elements of theAttributeListspecified, in the order in which they are returned by theAttributeList's iterator. TheAttributeListinstance has an initial capacity of 110% of the size of theAttributeListspecified.- Parameters:
list- theAttributeListthat defines the initial contents of the newAttributeList.- See Also:
ArrayList(java.util.Collection)
-
AttributeList
public AttributeList(List<Attribute> list)
Constructs anAttributeListcontaining the elements of theListspecified, in the order in which they are returned by theList's iterator.- Parameters:
list- theListthat defines the initial contents of the newAttributeList.- Throws:
IllegalArgumentException- if thelistparameter isnullor if thelistparameter 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 aList<Attribute>. Changes to the returned value are reflected by changes to the originalAttributeListand vice versa.- Returns:
- a
List<Attribute>whose contents reflect the contents of thisAttributeList.If this method has ever been called on a given
AttributeListinstance, a subsequent attempt to add an object to that instance which is not anAttributewill fail with anIllegalArgumentException. For compatibility reasons, anAttributeListon which this method has never been called does allow objects other thanAttributes to be added. - Throws:
IllegalArgumentException- if thisAttributeListcontains an element that is not anAttribute.- Since:
- 1.6
-
add
public void add(Attribute object)
Adds theAttributespecified 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- TheAttributeobject to be inserted.index- The position in the list where the newAttributeobject 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 theAttributeListspecified to the end of the list, in the order in which they are returned by the Iterator of theAttributeListspecified.- 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 theAttributeListspecified into this list, starting at the specified position, in the order in which they are returned by the Iterator of theAttributeListspecified. 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 theAttributeListspecified.- 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:
addin interfaceCollection<Object>- Specified by:
addin interfaceList<Object>- Overrides:
addin classArrayList<Object>- Parameters:
element- element to be appended to this list- Returns:
true(as specified byCollection.add(E))- Throws:
IllegalArgumentException- if thisAttributeListis type-safe andelementis not anAttribute.
-
add
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).
-
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.)- Specified by:
addAllin interfaceCollection<Object>- Specified by:
addAllin interfaceList<Object>- Overrides:
addAllin classArrayList<Object>- Parameters:
c- collection containing elements to be added to this list- Returns:
trueif this list changed as a result of the call- Throws:
IllegalArgumentException- if thisAttributeListis type-safe andccontains an element that is not anAttribute.- See Also:
AbstractCollection.add(Object)
-
addAll
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.- Specified by:
addAllin interfaceList<Object>- Overrides:
addAllin classArrayList<Object>- Parameters:
index- index at which to insert the first element from the specified collectionc- collection containing elements to be added to this list- Returns:
trueif this list changed as a result of the call- Throws:
IllegalArgumentException- if thisAttributeListis type-safe andccontains an element that is not anAttribute.
-
set
public Object set(int index, Object element)
Replaces the element at the specified position in this list with the specified element.- Specified by:
setin interfaceList<Object>- Overrides:
setin classArrayList<Object>- Parameters:
index- index of the element to replaceelement- element to be stored at the specified position- Returns:
- the element previously at the specified position
- Throws:
IllegalArgumentException- if thisAttributeListis type-safe andelementis not anAttribute.
