常量字段值

elementData

protected transient T extends Msg[] elementData

The array buffer into which the elements of the ArrayList are stored. The capacity of the ArrayList is the length of this array buffer.

size

protected int size

The size of the ArrayList (the number of elements it contains).

构造器详细资料

RemoteObjectList

public RemoteObjectList()

Constructs an empty list with an initial capacity of ten.

RemoteObjectList

public RemoteObjectList(Collection<T> c)

Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator. The ArrayList instance has an initial capacity of 110% the size of the specified collection.

参数:

c - the collection whose elements are to be placed into this list.

抛出:

NullPointerException - if the specified collection is null.

方法详细资料

trimToSize

public void trimToSize()

Trims the capacity of this ArrayList instance to be the list's current size. An application can use this operation to minimize the storage of an ArrayList instance.

ensureCapacity

public void ensureCapacity(int minCapacity)

Increases the capacity of this ArrayList instance, if necessary, to ensure that it can hold at least the number of elements specified by the minimum capacity argument.

参数:

minCapacity - the desired minimum capacity.

size

public int size()

Returns the number of elements in this list.

指定者:

size 在接口中 Collection<T extends Msg>

指定者:

size 在接口中 List<T extends Msg>

指定者:

size 在类中 AbstractCollection<T extends Msg>

返回:

the number of elements in this list.

isEmpty

public boolean isEmpty()

Tests if this list has no elements.

指定者:

isEmpty 在接口中 Collection<T extends Msg>

指定者:

isEmpty 在接口中 List<T extends Msg>

覆盖:

isEmpty 在类中 AbstractCollection<T extends Msg>

返回:

true if this list has no elements; false otherwise.

contains

public boolean contains(T elem)

Returns true if this list contains the specified element.

参数:

elem - element whose presence in this List is to be tested.

返回:

true if the specified element is present; false otherwise.

indexOf

public int indexOf(T elem)

Searches for the first occurence of the given argument, testing for equality using the equals method.

参数:

elem - an object.

返回:

the index of the first occurrence of the argument in this list; returns -1 if the object is not found.

另请参阅:

Object.equals(Object)

lastIndexOf

public int lastIndexOf(T elem)

Returns the index of the last occurrence of the specified object in this list.

参数:

elem - the desired element.

返回:

the index of the last occurrence of the specified object in this list; returns -1 if the object is not found.

clone

public Object clone()

Returns a shallow copy of this ArrayList instance. (The elements themselves are not copied.)

覆盖:

clone 在类中 Object

返回:

a clone of this ArrayList instance.

toArray

public T[] toArray()

Returns an array containing all of the elements in this list in the correct order.

指定者:

toArray 在接口中 Collection<T extends Msg>

指定者:

toArray 在接口中 List<T extends Msg>

覆盖:

toArray 在类中 AbstractCollection<T extends Msg>

返回:

an array containing all of the elements in this list in the correct order.

toArray

public T[] toArray(T[] a)

Returns an array containing all of the elements in this list in the correct order; the runtime type of the returned array is that of the specified array. If the list fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this list.

If the list fits in the specified array with room to spare (i.e., the array has more elements than the list), the element in the array immediately following the end of the collection is set to null. This is useful in determining the length of the list only if the caller knows that the list does not contain any null elements.

参数:

a - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose.

返回:

an array containing the elements of the list.

抛出:

ArrayStoreException - if the runtime type of a is not a supertype of the runtime type of every element in this list.

get

public T get(int index)

Returns the element at the specified position in this list.

指定者:

get 在接口中 List<T extends Msg>

指定者:

get 在类中 AbstractList<T extends Msg>

参数:

index - index of element to return.

返回:

the element at the specified position in this list.

抛出:

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

set

public T set(int index,
             T element)

Replaces the element at the specified position in this list with the specified element.

指定者:

set 在接口中 List<T extends Msg>

覆盖:

set 在类中 AbstractList<T extends Msg>

参数:

index - index of element to replace.

element - element to be stored at the specified position.

返回:

the element previously at the specified position.

抛出:

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

add

public boolean add(T o)

Appends the specified element to the end of this list.

指定者:

add 在接口中 Collection<T extends Msg>

指定者:

add 在接口中 List<T extends Msg>

覆盖:

add 在类中 AbstractList<T extends Msg>

参数:

o - element to be appended to this list.

返回:

true (as per the general contract of Collection.add).

add

public void add(int index,
                T element)

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

指定者:

add 在接口中 List<T extends Msg>

覆盖:

add 在类中 AbstractList<T extends Msg>

参数:

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

element - element to be inserted.

抛出:

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

remove

public T remove(int index)

Removes the element at the specified position in this list. Shifts any subsequent elements to the left (subtracts one from their indices).

指定者:

remove 在接口中 List<T extends Msg>

覆盖:

remove 在类中 AbstractList<T extends Msg>

参数:

index - the index of the element to removed.

返回:

the element that was removed from the list.

抛出:

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

clear

public void clear()

Removes all of the elements from this list. The list will be empty after this call returns.

指定者:

clear 在接口中 Collection<T extends Msg>

指定者:

clear 在接口中 List<T extends Msg>

覆盖:

clear 在类中 AbstractList<T extends Msg>

addAll

public boolean addAll(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. The behavior of this operation is undefined if the specified Collection is modified while the operation is in progress. (This implies that the behavior of this call is undefined if the specified Collection is this list, and this list is nonempty.)

指定者:

addAll 在接口中 Collection<T extends Msg>

指定者:

addAll 在接口中 List<T extends Msg>

覆盖:

addAll 在类中 AbstractCollection<T extends Msg>

参数:

c - the elements to be inserted into this list.

返回:

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

抛出:

NullPointerException - if the specified collection is null.

addAll

public boolean addAll(int index,
                      Collection c)

Inserts all of the elements in the specified Collection into this list, starting at the specified position. 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 the list in the order that they are returned by the specified Collection's iterator.

指定者:

addAll 在接口中 List<T extends Msg>

覆盖:

addAll 在类中 AbstractList<T extends Msg>

参数:

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

c - elements to be inserted into this list.

返回:

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

抛出:

IndexOutOfBoundsException - if index out of range (index < 0 || index > size()).

NullPointerException - if the specified Collection is null.

equals

public boolean equals(Object o)

指定者:

equals 在接口中 Collection<T extends Msg>

指定者:

equals 在接口中 List<T extends Msg>

覆盖:

equals 在类中 AbstractList<T extends Msg>

removeRange

protected void removeRange(int fromIndex,
                           int toIndex)

Removes from this List all of the elements whose index is between fromIndex, inclusive and toIndex, exclusive. Shifts any succeeding elements to the left (reduces their index). This call shortens the list by (toIndex - fromIndex) elements. (If toIndex==fromIndex, this operation has no effect.)

覆盖:

removeRange 在类中 AbstractList<T extends Msg>

参数:

fromIndex - index of first element to be removed.

toIndex - index after last element to be removed.
