Class RoleList

Constructors

RoleList

public RoleList()

Constructs an empty RoleList.

RoleList

public RoleList(int initialCapacity)

Constructs an empty RoleList with the initial capacity specified.

Parameters:

initialCapacity - initial capacity

RoleList

public RoleList(List<Role> list)
         throws IllegalArgumentException

Constructs a RoleList containing the elements of the List specified, in the order in which they are returned by the List's iterator. The RoleList instance has an initial capacity of 110% of the size of the List specified.

Parameters:

list - the List that defines the initial contents of the new RoleList.

Throws:

IllegalArgumentException - if the list parameter is null or if the list parameter contains any non-Role objects.

ArrayList(java.util.Collection)

Methods

asList

public List<Role> asList()

Return a view of this list as a List<Role>. Changes to the returned value are reflected by changes to the original RoleList and vice versa.

Returns:

a List<Role> whose contents reflect the contents of this RoleList.

If this method has ever been called on a given RoleList instance, a subsequent attempt to add an object to that instance which is not a Role will fail with an IllegalArgumentException. For compatibility reasons, a RoleList on which this method has never been called does allow objects other than Roles to be added.

Throws:

IllegalArgumentException - if this RoleList contains an element that is not a Role.

Since:

1.6

add

public void add(Role role)
         throws IllegalArgumentException

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

Parameters:

role - the role to be added.

Throws:

IllegalArgumentException - if the role is null.

add

public void add(int index,
                Role role)
         throws IllegalArgumentException,
                IndexOutOfBoundsException

Inserts the role specified as an element at the position specified. Elements with an index greater than or equal to the current position are shifted up.

Parameters:

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

role - The Role object to be inserted.

Throws:

IllegalArgumentException - if the role is null.

IndexOutOfBoundsException - if accessing with an index outside of the list.

set

public void set(int index,
                Role role)
         throws IllegalArgumentException,
                IndexOutOfBoundsException

Sets the element at the position specified to be the role specified. The previous element at that position is discarded.

Parameters:

index - The position specified.

role - The value to which the role element should be set.

Throws:

IllegalArgumentException - if the role is null.

IndexOutOfBoundsException - if accessing with an index outside of the list.

addAll

public boolean addAll(RoleList roleList)
               throws IndexOutOfBoundsException

Appends all the elements in the RoleList specified to the end of the list, in the order in which they are returned by the Iterator of the RoleList specified.

Parameters:

roleList - Elements to be inserted into the list (can be null)

Returns:

true if this list changed as a result of the call.

                      IndexOutOfBoundsException
