public abstract class AbstractCharCollection
extends AbstractCollection<Character>
implements CharCollection

An abstract class providing basic methods for collections implementing a type-specific interface.

In particular, this class provide iterator(), add(), remove(Object) and contains(Object) methods that just call the type-specific counterpart.

Method Detail

toArray

public char[] toArray(char[] a)

Specified by:

toArray in interface CharCollection

Parameters:

a - if this array is big enough, it will be used to store this collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

toCharArray

public char[] toCharArray()

Description copied from interface: CharCollection

Returns a primitive type array containing the items of this collection.

Specified by:

toCharArray in interface CharCollection

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toCharArray

public char[] toCharArray(char[] a)

Description copied from interface: CharCollection

Specified by:

toCharArray in interface CharCollection

Parameters:

a - if this array is big enough, it will be used to store this collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

addAll

public boolean addAll(CharCollection c)

Adds all elements of the given type-specific collection to this collection.

Specified by:

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.addAll(Collection)

containsAll

public boolean containsAll(CharCollection c)

Checks whether this collection contains all elements from the given type-specific collection.

Specified by:

containsAll in interface CharCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection contains all elements of the argument.

See Also:

Specified by:

retainAll in interface CharCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.retainAll(Collection)

removeAll

public boolean removeAll(CharCollection c)

Remove from this collection all elements in the given type-specific collection.

Specified by:

removeAll in interface CharCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.removeAll(Collection)

toArray

public Object[] toArray()

Specified by:

toArray in interface Collection<Character>

Overrides:

toArray in class AbstractCollection<Character>

toArray

public <T> T[] toArray(T[] a)

Description copied from interface: CharCollection

Returns an containing the items of this collection; the runtime type of the returned array is that of the specified array.

Warning: Note that, contrarily to Collection.toArray(Object[]), this methods just writes all elements of this collection: no special value will be added after the last one.

Specified by:

toArray in interface CharCollection

Specified by:

toArray in interface Collection<Character>

Overrides:

toArray in class AbstractCollection<Character>

Parameters:

a - if this array is big enough, it will be used to store this collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

addAll

public boolean addAll(Collection<? extends Character> c)

Adds all elements of the given collection to this collection.

Specified by:

addAll in interface Collection<Character>

Overrides:

addAll in class AbstractCollection<Character>

Parameters:

c - a collection.

Returns:

true if this collection changed as a result of the call.

add

public boolean add(char k)

Specified by:

add in interface CharCollection

See Also:

Collection.add(Object)

charIterator

@Deprecated
public CharIterator charIterator()

Deprecated.

Delegates to the new covariantly stronger generic method.

Specified by:

charIterator in interface CharCollection

See Also:

CharCollection.iterator()

iterator

public abstract CharIterator iterator()

Description copied from interface: CharCollection

Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

Specified by:

iterator in interface CharCollection

Specified by:

iterator in interface CharIterable

Specified by:

iterator in interface Collection<Character>

Specified by:

iterator in interface Iterable<Character>

Specified by:

iterator in class AbstractCollection<Character>

Returns:

a type-specific iterator on the elements of this collection.

remove

public boolean remove(Object ok)

Delegates to the type-specific rem() method.

Specified by:

remove in interface Collection<Character>

Overrides:

remove in class AbstractCollection<Character>

add

public boolean add(Character o)

Delegates to the corresponding type-specific method.

Specified by:

add in interface Collection<Character>

Overrides:

add in class AbstractCollection<Character>

rem

public boolean rem(Object o)

Delegates to the corresponding type-specific method.

contains

public boolean contains(Object o)

Delegates to the corresponding type-specific method.

Specified by:

contains in interface Collection<Character>

Overrides:

contains in class AbstractCollection<Character>

contains

public boolean contains(char k)

Specified by:

contains in interface CharCollection

See Also:

Collection.contains(Object)

rem

public boolean rem(char k)

Description copied from interface: CharCollection

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

Specified by:

rem in interface CharCollection

See Also:

Collection.remove(Object)
