List
A basic list container backed by either array list or linked list.
List type
list<Type >
Subtypes | Supertypes | Comparable types |
|---|---|---|
none | sequence<Type > | java.util.List<Type> |
List creation
new arraylist
new linkedlist
Parameter type | Result type |
|---|---|
Type...
{*}sequence<?extends *Type
> | list<Type > |
Creates an empty list. Optionally, initial values may be specified right in the new list creation expression.
list<Type> l = new arraylist<Type> { /* initial values */ };
Alternatively, a sequence may be specified that is used to copy elements from.
list<Type> = new arraylist<Type> (sequence);
Operations on list
iterator
Operand type | Parameter type | Result type |
|---|---|---|
sequence<Type > | none | modifying_iterator<Type > |
This operation is redefined for list to return a
get
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | int | Type |
Yields the element at index position.
list.get (index);
indexed access
list[index];
set
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | int Type | Type |
Sets the element at index position to the specified value. Yields the new value.
list.set (index, value);
indexed access
list[index] = value;
add
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | Type | Type |
Adds an element to the list.
list.add (value);
addFirst
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | Type | Type |
Adds an element to the list as the first element.
list.addFirst (value);
addLast
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | Type | Type |
Adds an element to the list as the last element.
list.addLast (value);
insert
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | int Type | Type |
Inserts an element into the list at the position index.
list.insert (index, value);
remove
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | Type | Type |
Removes an element from the list.
list.remove (value);
removeFirst
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | none | Type |
Removes the first element from the list.
list.removeFirst;
removeLast
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | none | Type |
Removes the last element from the list.
list.removeLast;
removeAt
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | int | Type |
Removes an element from the list located at the position index.
list.removeAt (index);
addAll
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | sequence<Type > | list<Type > |
Adds all elements in the parameter sequence to the list.
list.addAll (seq);
removeAll
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | sequence<Type > | list<Type > |
Removes all elements in the parameter sequence from the list.
list.removeAll (seq);
clear
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | none | void |
Clears all elements from the list.
list.clear;
reverse
Operand type | Parameter type | Result type |
|---|---|---|
list<Type > | none | list<Type > |
Produces a list with all elements from the original list in the reversed order.
list.reverse;
