public class IntegerList
extends AbstractList<Integer>
implements RandomAccess, Serializable, Cloneable

A list of unsigned integer values. This class packs the values in the minimal amount of bits required for storing unsigned integers of the given maximal value.

This class is not thread-safe. Synchronizations (if wanted) are user's reponsability.

Constructor Detail

IntegerList

public IntegerList(int initialCapacity,
                   int maximalValue)

Creates an initially empty list with the given initial capacity.

Parameters:

initialCapacity - The initial capacity.

maximalValue - The maximal value to be allowed, inclusive.

IntegerList

public IntegerList(int initialCapacity,
                   int maximalValue,
                   boolean fill)

Creates a new list with the given initial size. The value of all elements are initialized to 0.

Parameters:

initialCapacity - The initial capacity.

maximalValue - The maximal value to be allowed, inclusive.

fill - If true, the initial size is set to the initial capacity with all values set to 0.

Method Detail

maximalValue

public int maximalValue()

Returns the maximal value that can be stored in this list. May be slighly higher than the value given to the constructor.

Returns:

The maximal value, inclusive.

size

public int size()

Returns the current number of values in this list.

Specified by:

size in interface Collection<Integer>

Specified by:

size in interface List<Integer>

Specified by:

size in class AbstractCollection<Integer>

Returns:

The number of values.

resize

public void resize(int size)

Sets the list size to the given value. If the new size is lower than previous size, then the elements after the new size are discarted. If the new size is greater than the previous one, then the extra elements are initialized to 0.

Parameters:

size - The new size.

fill

public void fill(int value)

Fills the list with the given value. Every existing values are overwritten from index 0 inclusive up to size exclusive.

Parameters:

value - The value to set.

clear

public void clear()

Discarts all elements in this list.

Specified by:

clear in interface Collection<Integer>

Specified by:

clear in interface List<Integer>

Overrides:

clear in class AbstractList<Integer>

add

public boolean add(Integer value)
            throws IllegalArgumentException

Adds the given element to this list.

Specified by:

add in interface Collection<Integer>

Specified by:

add in interface List<Integer>

Overrides:

add in class AbstractList<Integer>

Parameters:

value - The value to add.

Throws:

NullPointerException - if the given value is null.

IllegalArgumentException - if the given value is out of bounds.

addInteger

public void addInteger(int value)
                throws IllegalArgumentException

Adds the given element as the int primitive type.

Parameters:

value - The value to add.

Throws:

IllegalArgumentException - if the given value is out of bounds.

get

public Integer get(int index)
            throws IndexOutOfBoundsException

Specified by:

get in interface List<Integer>

Specified by:

get in class AbstractList<Integer>

Parameters:

index - The element index.

Returns:

The value at the given index.

Throws:

IndexOutOfBoundsException - if the given index is out of bounds.

getInteger

            throws IndexOutOfBoundsException

Sets the element at the given index.

Specified by:

set in interface List<Integer>

Overrides:

set in class AbstractList<Integer>

Parameters:

index - The element index.

value - The value at the given index.

Returns:

The previous value at the given index.

Throws:

IndexOutOfBoundsException - if the given index is out of bounds.

IllegalArgumentException - if the given value is out of bounds.

NullPointerException - if the given value is null.

setInteger

Parameters:

value - The value to search for.

Returns:

The number of time the given value occurs in this list.

trimToSize
