Nested Class Summary

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

RandomAccessFloatList.RandomAccessFloatListIterator, RandomAccessFloatList.RandomAccessFloatSubList

Constructor Summary

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

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

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

Method Summary

void	add(int index, float 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.
float	get(int index) Returns the value of the element at the specified position within me.
float	removeElementAt(int index) Removes the element at the specified position in (optional operation).
float	set(int index, float 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

ArrayFloatList

public ArrayFloatList()

Construct an empty list with the default initial capacity.

ArrayFloatList

public ArrayFloatList(int initialCapacity)

Construct an empty list with the given initial capacity.

Throws:

IllegalArgumentException - when initialCapacity is negative

ArrayFloatList

public ArrayFloatList(FloatCollection 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 floats to add

Throws:

NullPointerException - if that is null

AbstractFloatCollection.addAll(org.apache.commons.collections.primitives.FloatCollection)

Method Detail

get

public float get(int index)

Description copied from interface: FloatList

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

Specified by:

get in interface FloatList

Specified by:

get in class RandomAccessFloatList

size

public int size()

Description copied from interface: FloatCollection

Returns the number of elements I contain.

Specified by:

size in interface FloatCollection

Specified by:

size in class RandomAccessFloatList

removeElementAt

public float 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 FloatList

Overrides:

removeElementAt in class RandomAccessFloatList

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 float set(int index,
                 float element)

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

Specified by:

set in interface FloatList

Overrides:

set in class RandomAccessFloatList

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,
                float 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 FloatList

Overrides:

add in class RandomAccessFloatList

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.
