Parameters: delegate The list that we will delegate requests to.
Lists that support this operation may place limitations on what elements may be added to this list. In particular, some lists will refuse to add null elements, and others will impose restrictions on the type of elements that may be added. List classes should clearly specify in their documentation any restrictions on what elements may be added.
Parameters: object element to be appended to this list.
Returns: true (as per the general contract of the Collection.add method).
Throws: UnsupportedOperationException if the add method is not supported by this list.
Parameters: index index at which the specified element is to be inserted. element element to be inserted.
Throws: UnsupportedOperationException if the add method is not supported by this list.
Parameters: collection collection whose elements are to be added to this list.
Returns: true if this list changed as a result of the call.
Throws: UnsupportedOperationException if the addAll method is not supported by this list.
See Also: add
Parameters: index index at which to insert first element from the specified collection. collection elements to be inserted into this list.
Returns: true if this list changed as a result of the call.
Throws: UnsupportedOperationException if the addAll method is not supported by this list.
Parameters: listener The listener to add.
Throws: UnsupportedOperationException if the clear method is not supported by this list.
Parameters: object element whose presence in this list is to be tested.
Returns: true if this list contains the specified element.
Parameters: collection collection to be checked for containment in this list.
Returns: true if this list contains all of the elements of the specified collection.
See Also: contains
Parameters: startIndex The first index oldValues The old values newValues The new values
Parameters: startIndex The first index insertCount The number of items being inserted
Parameters: startIndex The first index endIndex The last index objectsRemoved A list of all the objects that have been removd.
Parameters: index index of element to return.
Returns: the element at the specified position in this list.
Parameters: object element to search for.
Returns: the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element.
Returns: true if this list contains no elements.
Returns: an iterator over the elements in this list in proper sequence.
Parameters: object element to search for.
Returns: the index in this list of the last occurrence of the specified element, or -1 if this list does not contain this element.
Returns: a list iterator of the elements in this list (in proper sequence).
Parameters: index index of first element to be returned from the list iterator (by a call to the next method).
Returns: a list iterator of the elements in this list (in proper sequence), starting at the specified position in this list.
Parameters: index the index of the element to removed.
Returns: the element previously at the specified position.
Throws: UnsupportedOperationException if the remove method is not supported by this list.
Parameters: object element to be removed from this list, if present.
Returns: true if this list contained the specified element.
Throws: UnsupportedOperationException if the remove method is not supported by this list.
Parameters: collection collection that defines which elements will be removed from this list.
Returns: true if this list changed as a result of the call.
Throws: UnsupportedOperationException if the removeAll method is not supported by this list.
Parameters: listener The listener to remove.
Parameters: collection collection that defines which elements this set will retain.
Returns: true if this list changed as a result of the call.
Throws: UnsupportedOperationException if the retainAll method is not supported by this list.
Parameters: index index of element to replace. element element to be stored at the specified position.
Returns: the element previously at the specified position.
Throws: UnsupportedOperationException if the set method is not supported by this list.
Returns: the number of elements in this list.
This method eliminates the need for explicit range operations (of the sort that commonly exist for arrays). Any operation that expects a list can be used as a range operation by passing a subList view instead of a whole list. For example, the following idiom removes a range of elements from a list:
list.subList(from, to).clear();Similar idioms may be constructed for indexOf and lastIndexOf, and all of the algorithms in the Collections class can be applied to a subList.
The semantics of this list returned by this method become undefined if the backing list (i.e., this list) is structurally modified in any way other than via the returned list. (Structural modifications are those that change the size of this list, or otherwise perturb it in such a fashion that iterations in progress may yield incorrect results.)
Parameters: fromIndex low endpoint (inclusive) of the subList. toIndex high endpoint (exclusive) of the subList.
Returns: a view of the specified range within this list.
Returns: an array containing all of the elements in this list in proper sequence.
See Also: List#toArray(Object[])
Parameters: array the array into which the elements of this list are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose.
Returns: an array containing the elements of this list.
Throws: ArrayStoreException if the runtime type of the specified array is not a supertype of the runtime type of every element in this list.
