All Implemented Interfaces:

Cloneable, Iterable<Character>, Collection<Character>, CharCollection, PrimitiveCollection<Character>, CharIterable, PrimitiveCollectable<Character>

public class ArrayCharCollection
extends AbstractCharCollection
implements Cloneable

Array based implementation of CharCollection for primitive char elements.

This collection implementation allows multiple copies of the same value to be added. Internally, it uses an array, and behaves much like a list.

This class implements Collection allowing seamless integration with other APIs.

Add, Remove and Clear are supported.

Constructor Detail

ArrayCharCollection

public ArrayCharCollection()

Constructor.

ArrayCharCollection

public ArrayCharCollection(int initialSize)

Constructor that defines an initial size for the internal storage array.

Parameters:

initialSize - the initial size of the internal array, negative treated as zero

ArrayCharCollection

public ArrayCharCollection(char[] values)

Constructor that copies the specified values.

Parameters:

values - an array of values to copy, null treated as zero size array

ArrayCharCollection

public ArrayCharCollection(Collection<?> coll)

Constructs a new collection by copying values from another collection.

Parameters:

coll - a collection of values to copy, null treated as zero size collection

ArrayCharCollection

public ArrayCharCollection(Iterator<Character> it)

Constructs a new collection by copying values from an iterator.

Parameters:

it - an iterator of values to extract, null treated as zero size collection

Method Detail

size

public int size()

Gets the current size of the collection.

Specified by:

size in interface Collection<Character>

Specified by:

size in interface PrimitiveCollectable<Character>

Returns:

the current size

iterator

public CharIterator iterator()

Gets an iterator over this collection capable of accessing the primitive values.

Specified by:

iterator in interface Iterable<Character>

Specified by:

iterator in interface Collection<Character>

Specified by:

iterator in interface CharCollection

Specified by:

iterator in interface CharIterable

Returns:

an iterator over this collection

add

public boolean add(char value)

Adds a primitive value to this collection.

Specified by:

add in interface CharCollection

Overrides:

add in class AbstractCharCollection

Parameters:

value - the value to add to this collection

Returns:

true if this collection was modified by this method call

Throws:

IllegalArgumentException - if value is rejected by this collection

optimize

public void optimize()

Optimizes the implementation.

This implementation changes the internal array to be the same size as the size of the collection.

Specified by:

optimize in interface PrimitiveCollectable<Character>

Overrides:

optimize in class AbstractPrimitiveCollectable<Character>

isAddModifiable

protected boolean isAddModifiable()

Are the add methods supported.

Overrides:

isAddModifiable in class AbstractCharCollection

Returns:

true

isRemoveModifiable

protected boolean isRemoveModifiable()

Are the remove methods supported.

Overrides:

isRemoveModifiable in class AbstractCharCollection

Returns:

true

isModifiable

public boolean isModifiable()

Checks whether the object can currently be modified.

Specified by:

isModifiable in interface PrimitiveCollectable<Character>

Overrides:

isModifiable in class AbstractCharCollection

Returns:

true

contains

public boolean contains(char value)

Checks whether this collection contains a specified primitive value.

This implementation uses the internal array directly.

Specified by:

contains in interface CharCollection

Overrides:

contains in class AbstractCharCollection

Parameters:

value - the value to search for

Returns:

true if the value is found

clear

public void clear()

Clears the collection of all elements. The collection will have a zero size after this method completes.

This implementation resets the size, but does not reduce the internal storage array.

Specified by:

clear in interface Collection<Character>

Specified by:

clear in interface PrimitiveCollectable<Character>

Overrides:

clear in class AbstractCharCollection

addAll

public boolean addAll(char[] values)

Adds an array of primitive values to this collection.

Specified by:

addAll in interface CharCollection

Overrides:

addAll in class AbstractCharCollection

Parameters:

values - the values to add to this collection

Returns:

true if this collection was modified by this method call

addAll

public boolean addAll(CharCollection values)

Adds a collection of primitive values to this collection.

Specified by:

addAll in interface CharCollection

Overrides:

addAll in class AbstractCharCollection

Parameters:

values - the values to add to this collection, null treated as empty collection

Returns:

true if this collection was modified by this method call

addAll

public boolean addAll(char startInclusive,
             char endInclusive)

Adds a range of primitive values to this collection.

The range is defined to be inclusive of the start and end. If the start is greater than the end then the range is equivalent to an empty collection.

Specified by:

addAll in interface CharCollection

Overrides:

addAll in class AbstractCharCollection

Parameters:

startInclusive - the inclusive range start value

endInclusive - the inclusive range end value

Returns:

true if this collection was modified by this method call

Throws:

IllegalArgumentException - if a value is rejected by this set

UnsupportedOperationException - if not supported by this set

clone

public Object clone()

Clone implementation that calls Object clone().

Specified by:

clone in interface PrimitiveCollectable<Character>

Overrides:

clone in class AbstractPrimitiveCollectable<Character>

             int destIndex,
             int size)

Copies data from this collection into the specified array. This method is pre-validated.

Overrides:

arrayCopy in class AbstractCharCollection

Parameters:

fromIndex - the index to start from

dest - the destination array
