public AbstractBasicUnmodifiableList()

Method Detail

clear

public void clear()

Removes all of the elements from this list (optional operation). This list will be empty after this call returns (unless it throws an exception).

Specified by:

clear in interface java.util.Collection<T>

Specified by:

clear in interface java.util.List<T>

Throws:

java.lang.UnsupportedOperationException - if the clear method is not supported by this list.

remove

public T remove(int index)

Removes the element at the specified position in this list (optional operation). Shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the list.

Specified by:

remove in interface java.util.List<T>

Parameters:

index - the index of the element to removed.

Returns:

the element previously at the specified position.

Throws:

java.lang.UnsupportedOperationException - if the remove method is not supported by this list.

java.lang.IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= size()).

remove

public boolean remove(java.lang.Object o)

Removes the first occurrence in this list of the specified element (optional operation). If this list does not contain the element, it is unchanged. More formally, removes the element with the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))) (if such an element exists).

Specified by:

remove in interface java.util.Collection<T>

Specified by:

remove in interface java.util.List<T>

Parameters:

o - element to be removed from this list, if present.

Returns:

true if this list contained the specified element.

Throws:

java.lang.ClassCastException - if the type of the specified element is incompatible with this list (optional).

java.lang.NullPointerException - if the specified element is null and this list does not support null elements (optional).

java.lang.UnsupportedOperationException - if the remove method is not supported by this list.

addAll

public boolean addAll(int index,
                      @NotNull
                      java.util.Collection<? extends T> c)

Inserts all of the elements in the specified collection into this list at the specified position (optional operation). 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 this list in the order that they are returned by the specified collection's iterator. The behavior of this operation is unspecified if the specified collection is modified while the operation is in progress. (Note that this will occur if the specified collection is this list, and it's nonempty.)

Specified by:

addAll in interface java.util.List<T>

Parameters:

index - index at which to insert first element from the specified collection.

c - elements to be inserted into this list.

Returns:

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

Throws:

java.lang.UnsupportedOperationException - if the addAll method is not supported by this list.

java.lang.ClassCastException - if the class of one of elements of the specified collection prevents it from being added to this list.

java.lang.NullPointerException - if the specified collection contains one or more null elements and this list does not support null elements, or if the specified collection is null.

java.lang.IllegalArgumentException - if some aspect of one of elements of the specified collection prevents it from being added to this list.

java.lang.IndexOutOfBoundsException - if the index is out of range (index < 0 || index > size()).

addAll

public boolean addAll(@NotNull
                      java.util.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 (optional operation). The behavior of this operation is unspecified if the specified collection is modified while the operation is in progress. (Note that this will occur if the specified collection is this list, and it's nonempty.)

Specified by:

addAll in interface java.util.Collection<T>

Specified by:

addAll in interface java.util.List<T>

Parameters:

c - collection whose elements are to be added to this list.

Returns:

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

Throws:

java.lang.UnsupportedOperationException - if the addAll method is not supported by this list.

java.lang.ClassCastException - if the class of an element in the specified collection prevents it from being added to this list.

java.lang.NullPointerException - if the specified collection contains one or more null elements and this list does not support null elements, or if the specified collection is null.

java.lang.IllegalArgumentException - if some aspect of an element in the specified collection prevents it from being added to this list.

removeAll

public boolean removeAll(@NotNull
                         java.util.Collection c)

Removes from this list all the elements that are contained in the specified collection (optional operation).

Specified by:

removeAll in interface java.util.Collection<T>

Specified by:

removeAll in interface java.util.List<T>

Parameters:

c - collection that defines which elements will be removed from this list.

Returns:

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

Throws:

java.lang.UnsupportedOperationException - if the removeAll method is not supported by this list.

java.lang.ClassCastException - if the types of one or more elements in this list are incompatible with the specified collection (optional).

java.lang.NullPointerException - if this list contains one or more null elements and the specified collection does not support null elements (optional). or if the specified collection is null.

remove(Object), List.contains(Object)

retainAll

public boolean retainAll(@NotNull
                         java.util.Collection c)

Retains only the elements in this list that are contained in the specified collection (optional operation). In other words, removes from this list all the elements that are not contained in the specified collection.

Specified by:

retainAll in interface java.util.Collection<T>

Specified by:

retainAll in interface java.util.List<T>

Parameters:

c - collection that defines which elements this set will retain.

add

public void add(int index,
                T element)

Inserts the specified element at the specified position in this list (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

Specified by:

add in interface java.util.List<T>

Parameters:

index - index at which the specified element is to be inserted.

element - element to be inserted.

Throws:

java.lang.UnsupportedOperationException - if the add method is not supported by this list.

add

public boolean add(T o)

Appends the specified element to the end of this list (optional operation).

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.

Specified by:

add in interface java.util.Collection<T>

Specified by:

add in interface java.util.List<T>
