javax.media.j3d .UnorderList

UnorderList

class UnorderList implements Cloneable,java.io.Serializable(Code)

A strongly type unorder array list. The operation add(Object o) & remove(int i) take O(1) time. The class is designed to optimize speed. So many reductance procedures call and range check as found in ArrayList are removed.

Use the following code to iterate through an array.

 UnorderList  list = new UnorderList(YourClass.class);
 // add element here
 YourClass[] arr = (YourClass []) list.toArray();
 int size = list.arraySize();
 for (int i=0; i < size; i++) {
 YourClass obj = arr[i];
 ....
 }

Note:

Field Detail

cloneData
transient Object cloneData(Code)
	Clone copy of elementData return by toArray(true);

cloneSize
transient int cloneSize(Code)

componentType
Class componentType(Code)
	Component Type of individual array element entry

elementData
transient Object elementData(Code)
	The array buffer into which the elements of the ArrayList are stored. The capacity of the ArrayList is the length of this array buffer. It is non-private to enable compiler do inlining for get(), set(), remove() when -O flag turn on.

isDirty
transient boolean isDirty(Code)

size
int size(Code)
	The size of the ArrayList (the number of elements it contains). We make it non-private to enable compiler do inlining for getSize() when -O flag turn on.

Constructor Detail

UnorderList
UnorderList(int initialCapacity, Class componentType)(Code)
	Constructs an empty list with the specified initial capacity. and the class data Type Parameters: initialCapacity - the initial capacity of the list. Parameters: componentType - class type of element in the list.

UnorderList
UnorderList(Class componentType)(Code)
	Constructs an empty list. Parameters: componentType - class type of element in the list.

UnorderList
UnorderList(int initialCapacity)(Code)
	Constructs an empty list with the specified initial capacity. Parameters: initialCapacity - the initial capacity of the list.

UnorderList
UnorderList()(Code)
	Constructs an empty list. componentType default to Object.

Method Detail

add
final synchronized void add(Object o)(Code)
	Appends the specified element to the end of this list. It is the user responsible to ensure that the element add is of the same type as array componentType. Parameters: o - element to be appended to this list.

addUnique
final synchronized boolean addUnique(Object o)(Code)
	Add Object into the list if it is not already exists. Parameters: o - an object to add into the list true if object successfully add, false if duplicate found

arraySize
final int arraySize()(Code)
	Returns the size of entry use in toArray() number of elements in this list. the number of elements in this list.

clear
final synchronized void clear()(Code)
	Removes all of the elements from this list. The list will be empty after this call returns.

clearMirror
final synchronized void clearMirror()(Code)

clone
final protected synchronized Object clone()(Code)
	Returns a shallow copy of this `ArrayList` instance. (The elements themselves are not copied.) a clone of this `ArrayList` instance.

contains
final synchronized boolean contains(Object o)(Code)
	Returns `true` if this list contains the specified element. Parameters: o - element whose presence in this List is to be tested.

get
final synchronized Object get(int index)(Code)
	Returns the element at the specified position in this list. Parameters: index - index of element to return. the element at the specified position in this list. throws: IndexOutOfBoundsException - if index is out of range `(index< 0 \|\| index >= size())`.

getComponentType
final Class getComponentType()(Code)

indexOf
final synchronized int indexOf(Object o)(Code)
	Searches for the last occurence of the given argument, testing for equality using the `equals` method. Parameters: o - an object. the index of the first occurrence of the argument in thislist; returns `-1` if the object is not found. See Also: Object.equals(Object)

isEmpty
final boolean isEmpty()(Code)

remove
final synchronized boolean remove(Object o)(Code)
	Removes the specified element in this list. Replace the removed element by the last one. Parameters: o - the element to removed. true if object remove throws: IndexOutOfBoundsException - if index out of range `(index< 0 \|\| index >= size())`.

removeLastElement
final synchronized Object removeLastElement()(Code)
	Removes the element at the last position in this list. The element remove throws: IndexOutOfBoundsException - if array is empty

removeOrdered
final synchronized void removeOrdered(int index)(Code)
	Removes the element at the specified position in this list. The order is keep. Parameters: index - the index of the element to removed. throws: IndexOutOfBoundsException - if index out of range `(index< 0 \|\| index >= size())`.

set
final synchronized void set(int index, Object element)(Code)
	Replaces the element at the specified position in this list with the specified element. Parameters: index - index of element to replace. Parameters: element - element to be stored at the specified position. the element previously at the specified position. throws: IndexOutOfBoundsException - if index out of range`(index < 0 \|\| index >= size())`.

shift
final synchronized void shift(Object objs, int idx)(Code)

size
final int size()(Code)
	Returns the number of elements in this list. the number of elements in this list.

toArray
final synchronized Object[] toArray(boolean copy)(Code)
	Returns an array containing all of the elements in this list. The size of the array may longer than the actual size. Use arraySize() to retrieve the size. The array return is a copied of internal array. if copy is true. an array containing all of the elements in this list

toArray
final synchronized Object[] toArray()(Code)
	Returns an array containing all of the elements in this list. The size of the array may longer than the actual size. Use arraySize() to retrieve the size. The array return is a copied of internal array. So another thread can continue add/delete the current list. However, it should be noticed that two call to toArray() may return the same copy. an array containing all of the elements in this list

toArray
final synchronized Object[] toArray(Object startElement)(Code)
	Returns an array containing elements starting from startElement all of the elements in this list. A new array of exact size is always allocated. Parameters: startElement - starting element to copy an array containing elements starting fromstartElement, null if element not found.

toArrayAndClear
final synchronized void toArrayAndClear(Object[] objs)(Code)

toString
public synchronized String toString()(Code)

trimToSize
final synchronized void trimToSize()(Code)
	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.
