getElements

public void getElements(int from,
Object[] a,
int offset,
int length)

Description copied from interface: ReferenceList

Copies (hopefully quickly) elements of this type-specific list into the given array.

Specified by:

getElements in interface ReferenceList<K>

Parameters:

from - the start index (inclusive).

a - the destination array.

offset - the offset into the destination array where to store the first element copied.

length - the number of elements to be copied.

removeElements

public void removeElements(int from,
int to)

Description copied from interface: ReferenceList

Removes (hopefully quickly) elements of this type-specific list.

Specified by:

removeElements in interface ReferenceList<K>

Parameters:

from - the start index (inclusive).

to - the end index (exclusive).

addElements

public void addElements(int index,
K[] a,
int offset,
int length)

Description copied from interface: ReferenceList

Add (hopefully quickly) elements to this type-specific list.

Specified by:

addElements in interface ReferenceList<K>

Parameters:

index - the index at which to add elements.

a - the array containing the elements.

offset - the offset of the first element to add.

length - the number of elements to add.

addElements

public void addElements(int index,
K[] a)

Description copied from interface: ReferenceList

Add (hopefully quickly) elements to this type-specific list.

Specified by:

addElements in interface ReferenceList<K>

Parameters:

index - the index at which to add elements.

a - the array containing the elements.

setElements

public void setElements(K[] a)

Description copied from interface: ReferenceList

Set (hopefully quickly) elements to match the array given.

Specified by:

setElements in interface ReferenceList<K>

Parameters:

a - the array containing the elements.

setElements

public void setElements(int index,
K[] a)

Description copied from interface: ReferenceList

Set (hopefully quickly) elements to match the array given.

Specified by:

setElements in interface ReferenceList<K>

Parameters:

index - the index at which to start setting elements.

a - the array containing the elements.

setElements

public void setElements(int index,
K[] a,
int offset,
int length)

Description copied from interface: ReferenceList

Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if by

 
 ListIterator iter = listIterator(index);
 int i = 0;
 while (i < length) {
   iter.next();
   iter.set(a[offset + i++]);
 }
 
 

However, the exact implementation may be more efficient, taking into account whether random access is faster or not, or at the discretion of subclasses, abuse internals.

Specified by:

setElements in interface ReferenceList<K>

Parameters:

index - the index at which to start setting elements.

a - the array containing the elements

offset - the offset of the first element to add.

length - the number of elements to add.

size

public void size(int size)

Description copied from interface: ReferenceList

Sets the size of this list.

If the specified size is smaller than the current size, the last elements are discarded. Otherwise, they are filled with 0/null/false.

Specified by:

size in interface ReferenceList<K>

Parameters:

size - the new size.

listIterator

public ObjectListIterator<K> listIterator()

Description copied from interface: ReferenceList

Returns a type-specific list iterator on the list.

Specified by:

listIterator in interface List<K>

Specified by:

listIterator in interface ReferenceList<K>

See Also:

List.listIterator()

iterator

public ObjectListIterator<K> iterator()

Description copied from interface: ReferenceCollection

Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

Specified by:

iterator in interface Collection<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface List<K>

Specified by:

iterator in interface ObjectIterable<K>

Specified by:

iterator in interface ReferenceCollection<K>

Specified by:

iterator in interface ReferenceList<K>

Overrides:

iterator in class ReferenceCollections.UnmodifiableCollection<K>

Returns:

a type-specific iterator on the elements of this collection.

See Also:

Iterable.iterator()

listIterator

public ObjectListIterator<K> listIterator(int i)

Description copied from interface: ReferenceList

Returns a type-specific list iterator on the list starting at a given index.

Specified by:

listIterator in interface List<K>

Specified by:

listIterator in interface ReferenceList<K>

See Also:

List.listIterator(int)

subList

public ReferenceList<K> subList(int from,
int to)

Description copied from interface: ReferenceList

Returns a type-specific view of the portion of this list from the index from, inclusive, to the index to, exclusive.

Note that this specification strengthens the one given in List.subList(int,int).

Specified by:

subList in interface List<K>

Specified by:

subList in interface ReferenceList<K>

See Also:

List.subList(int,int)

equals

public boolean equals(Object o)

Specified by:

equals in interface Collection<K>

Specified by:

equals in interface List<K>

Overrides:

equals in class ReferenceCollections.UnmodifiableCollection<K>

hashCode

public int hashCode()

Specified by:

hashCode in interface Collection<K>

Specified by:

hashCode in interface List<K>

Overrides:

hashCode in class ReferenceCollections.UnmodifiableCollection<K>

sort

public void sort(Comparator<? super K> comparator)

Specified by:

sort in interface List<K>

unstableSort

public void unstableSort(Comparator<? super K> comparator)

Description copied from interface: ReferenceList

Sorts this list using a sort not assured to be stable. This differs from List.sort(java.util.Comparator) in that the results are not assured to be stable, but may be a bit faster.

Unless a subclass specifies otherwise, the results of the method if the list is concurrently modified during the sort are unspecified.

Specified by:

unstableSort in interface ReferenceList<K>
