类 SortedArrayList<E>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractList<E>

java.util.ArrayList<E>

cn.webfuse.core.lang.SortedArrayList<E>

所有已实现的接口:

Serializable, Cloneable, Iterable<E>, Collection<E>, List<E>, RandomAccess

public final class SortedArrayList<E>
extends ArrayList<E>

从Jodd整体复制，部分指定了index的操作不支持，如 add(index, element)

修改包括：改进Comparator泛型定义，findInsertionPoint的位移改进

https://github.com/oblac/jodd/blob/master/jodd-core/src/main/java/jodd/util/collection/SortedArrayList.java

An extension of ArrayList that insures that all of the items added are sorted. This breaks original list contract!. A binary search method is used to provide a quick way to auto sort this list.Note: Not all methods for adding and removing elements are supported.

SortedArrayList

public SortedArrayList(Comparator<? super E> c)

Constructs a new SortedArrayList.

SortedArrayList

public SortedArrayList()

Constructs a new SortedArrayList expecting elements are comparable.

SortedArrayList

public SortedArrayList(Collection<? extends E> c)

Constructs a new SortedArrayList expecting elements are comparable.

方法详细资料

getComparator

public Comparator getComparator()

Returns comparator assigned to this collection, if such exist.

add

public boolean add(E o)

Adds an Object to sorted list. Object is inserted at correct place, found using binary search. If the same item exist, it will be put to the end of the range.

This method breaks original list contract since objects are not added at the list end, but in sorted manner.

指定者:

add 在接口中 Collection<E>

指定者:

add 在接口中 List<E>

覆盖:

add 在类中 ArrayList<E>

addAll

public boolean addAll(Collection<? extends E> c)

Add all of the elements in the given collection to this list.

指定者:

addAll 在接口中 Collection<E>

指定者:

addAll 在接口中 List<E>

覆盖:

addAll 在类中 ArrayList<E>

findInsertionPoint

public int findInsertionPoint(E o)

Finds the index at which object should be inserted.

add

@Deprecated
public void add(int index,
                            E element)

已过时。

指定者:

add 在接口中 List<E>

覆盖:

add 在类中 ArrayList<E>

抛出:

UnsupportedOperationException - This method not supported.

set

@Deprecated
public E set(int index,
                         E element)

已过时。

指定者:

set 在接口中 List<E>

覆盖:

set 在类中 ArrayList<E>

抛出:

UnsupportedOperationException - This method not supported.

addAll

@Deprecated
public boolean addAll(int index,
                                  Collection<? extends E> c)

已过时。

指定者:

addAll 在接口中 List<E>

覆盖:

addAll 在类中 ArrayList<E>

抛出:

UnsupportedOperationException - This method not supported.

compare

protected int compare(E k1,
                      E k2)

Compares two keys using the correct comparison method for this collection.

findInsertionPoint

protected int findInsertionPoint(E o,
                                 int originalLow,
                                 int originalHigh)

Conducts a binary search to find the index where Object should be inserted.
