Constructor Detail

FastList

public FastList(Class<?> clazz)

Construct a FastList with a default size of 32.

Parameters:

clazz - the Class stored in the collection

FastList

public FastList(Class<?> clazz,
        int capacity)

Construct a FastList with a specified size.

Parameters:

clazz - the Class stored in the collection

capacity - the initial size of the FastList

Method Detail

add

public boolean add(T element)

Add an element to the tail of the FastList.

Specified by:

add in interface Collection<T>

Specified by:

add in interface List<T>

Parameters:

element - the element to add

get

public T get(int index)

Get the element at the specified index.

Specified by:

get in interface List<T>

Parameters:

index - the index of the element to get

Returns:

the element, or ArrayIndexOutOfBounds is thrown if the index is invalid

removeLast

public T removeLast()

Remove the last element from the list. No bound check is performed, so if this method is called on an empty list and ArrayIndexOutOfBounds exception will be thrown.

Returns:

the last element of the list

remove

public boolean remove(Object element)

This remove method is most efficient when the element being removed is the last element. Equality is identity based, not equals() based. Only the first matching element is removed.

Specified by:

remove in interface Collection<T>

Specified by:

remove in interface List<T>

Parameters:

element - the element to remove

clear

public void clear()

Clear the FastList.

Specified by:

clear in interface Collection<T>

Specified by:

clear in interface List<T>

size

public int size()

Get the current number of elements in the FastList.

Specified by:

size in interface Collection<T>

Specified by:

size in interface List<T>

Returns:

the number of current elements

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Collection<T>

Specified by:

isEmpty in interface List<T>

set

public T set(int index,
    T element)

Specified by:

set in interface List<T>

remove

public T remove(int index)

Specified by:

remove in interface List<T>

contains

public boolean contains(Object o)

Specified by:

contains in interface Collection<T>

Specified by:

contains in interface List<T>

iterator

public Iterator<T> iterator()

Specified by:
