Nested Class Summary

Nested classes inherited from class org.apache.commons.collections.primitives.RandomAccessShortList

RandomAccessShortList.RandomAccessShortListIterator, RandomAccessShortList.RandomAccessShortSubList

Constructor Summary

ArrayShortList()
Construct an empty list with the default initial capacity.

ArrayShortList(int initialCapacity)
Construct an empty list with the given initial capacity.

ArrayShortList(ShortCollection that)
Constructs a list containing the elements of the given collection, in the order they are returned by that collection's iterator.

Method Summary

void	add(int index, short element) Inserts the specified element at the specified position (optional operation).
void	ensureCapacity(int mincap) Increases my capacity, if necessary, to ensure that I can hold at least the number of elements specified by the minimum capacity argument without growing.
short	get(int index) Returns the value of the element at the specified position within me.
short	removeElementAt(int index) Removes the element at the specified position in (optional operation).
short	set(int index, short element) Replaces the element at the specified position in me with the specified element (optional operation).
int	size() Returns the number of elements I contain.
void	trimToSize() Reduce my capacity, if necessary, to match my current size.

Constructor Detail

ArrayShortList

public ArrayShortList()

Construct an empty list with the default initial capacity.

ArrayShortList

public ArrayShortList(int initialCapacity)

Construct an empty list with the given initial capacity.

Throws:

IllegalArgumentException - when initialCapacity is negative

ArrayShortList

public ArrayShortList(ShortCollection that)

Constructs a list containing the elements of the given collection, in the order they are returned by that collection's iterator.

Parameters:

that - the non-null collection of shorts to add

Throws:

NullPointerException - if that is null

AbstractShortCollection.addAll(org.apache.commons.collections.primitives.ShortCollection)

Method Detail

get

public short get(int index)

Description copied from interface: ShortList

Returns the value of the element at the specified position within me.

Specified by:

get in interface ShortList

Specified by:

get in class RandomAccessShortList

size

public int size()

Description copied from interface: ShortCollection

Returns the number of elements I contain.

Specified by:

size in interface ShortCollection

Specified by:

size in class RandomAccessShortList

removeElementAt

public short removeElementAt(int index)

Removes the element at the specified position in (optional operation). Any subsequent elements are shifted to the left, subtracting one from their indices. Returns the element that was removed.

Specified by:

removeElementAt in interface ShortList

Overrides:

removeElementAt in class RandomAccessShortList

Parameters:

index - the index of the element to remove

Returns:

the value of the element that was removed

Throws:

UnsupportedOperationException - when this operation is not supported

IndexOutOfBoundsException - if the specified index is out of range

set

public short set(int index,
                 short element)

Replaces the element at the specified position in me with the specified element (optional operation).

Specified by:

set in interface ShortList

Overrides:

set in class RandomAccessShortList

Parameters:

index - the index of the element to change

element - the value to be stored at the specified position

Returns:

the value previously stored at the specified position

Throws:

UnsupportedOperationException - when this operation is not supported

IndexOutOfBoundsException - if the specified index is out of range

add

public void add(int index,
                short element)

Inserts the specified element at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices.

Specified by:

add in interface ShortList

Overrides:

add in class RandomAccessShortList

Parameters:

index - the index at which to insert the element

element - the value to insert

Throws:

UnsupportedOperationException - when this operation is not supported

IllegalArgumentException - if some aspect of the specified element prevents it from being added to me

IndexOutOfBoundsException - if the specified index is out of range

ensureCapacity

public void ensureCapacity(int mincap)

Increases my capacity, if necessary, to ensure that I can hold at least the number of elements specified by the minimum capacity argument without growing.

trimToSize

public void trimToSize()

Reduce my capacity, if necessary, to match my current size.
