java.lang.Object
E - the element typepublic class CopyOnWriteArrayIdentityList<E>
Implements a ArrayList variant that is thread-safe. All
write operation result in a new copy of the underlying data being created.
Iterators reflect the state of the CopyOnWriteArrayIdentityList at the time they were
created. They are not updated to reflect subsequent changes to the list. In
addition, these iterators cannot be used for modifying the underlying
CopyOnWriteArrayIdentityList.
In addition, elements are compared based on reference equality instead of
object equality when comparing values.
| Constructor Summary | |
|---|---|
CopyOnWriteArrayIdentityList()

|
CopyOnWriteArrayIdentityList(Collection<? extends E> c)
Creates a new instance of CopyOnWriteArrayList and fills it with the contents of a given Collection. |
|
CopyOnWriteArrayIdentityList(E[] array)
Creates a new instance of CopyOnWriteArrayList and fills it with the contents of a given array. |
