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:
java.lang.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:
java.lang.NullPointerException - if that is null
See Also:
addAll(org.apache.commons.collections.primitives.FloatCollection)

ArrayFloatList

public ArrayFloatList(float[] array)
Constructs a list by copying the specified array.

Parameters:
array - the array to initialize the collection with
Throws:
java.lang.NullPointerException - if the array is null
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
Parameters:
index - the index of the element to return
Returns:
the value of the element at the specified position

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
Returns:
the number of elements I contain

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:
java.lang.UnsupportedOperationException - when this operation is not supported
java.lang.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:
java.lang.UnsupportedOperationException - when this operation is not supported
java.lang.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:
java.lang.UnsupportedOperationException - when this operation is not supported
java.lang.IllegalArgumentException - if some aspect of the specified element prevents it from being added to me
java.lang.IndexOutOfBoundsException - if the specified index is out of range

clear

public void clear()
Description copied from interface: FloatCollection
Removes all my elements (optional operation). I will be empty after this method successfully returns.

Specified by:
clear in interface FloatCollection
Overrides:
clear in class AbstractFloatCollection

addAll

public boolean addAll(FloatCollection collection)
Description copied from interface: FloatCollection
Adds all of the elements in the specified collection to me (optional operation).

Specified by:
addAll in interface FloatCollection
Overrides:
addAll in class AbstractFloatCollection
Parameters:
collection - the collection of elements whose presence within me is to be ensured
Returns:
true iff I changed as a result of this call

addAll

public boolean addAll(int index,
                      FloatCollection collection)
Description copied from interface: FloatList
Inserts all of the elements in the specified collection into me, 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. The new elements will appear in the order that they are returned by the given collection's iterator.

Specified by:
addAll in interface FloatList
Overrides:
addAll in class RandomAccessFloatList
Parameters:
index - the index at which to insert the first element from the specified collection
collection - the FloatCollection of elements to add
Returns:
true iff I changed as a result of this call

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.
