Method Detail

size

public int size()
Specified by:
size in interface java.util.Collection<java.lang.Character>

isEmpty

public boolean isEmpty()
Specified by:
isEmpty in interface java.util.Collection<java.lang.Character>

contains

public boolean contains(char o)
Specified by:
contains in interface CharCollection
See Also:
Collection.contains(Object)

iterator

public 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 java.lang.Iterable<java.lang.Character>
Specified by:
iterator in interface java.util.Collection<java.lang.Character>
Returns:
a type-specific iterator on the elements of this collection.

charIterator

@Deprecated
public CharIterator charIterator()
Deprecated. 

Description copied from interface: CharCollection
Returns a type-specific iterator on this elements of this collection.

Specified by:
charIterator in interface CharCollection
See Also:
CharCollection.iterator()

add

public boolean add(char k)
Specified by:
add in interface CharCollection
See Also:

Specified by:
remove in interface java.util.Collection<java.lang.Character>

addAll

public boolean addAll(java.util.Collection<? extends java.lang.Character> c)
Specified by:
addAll in interface java.util.Collection<java.lang.Character>

containsAll

public boolean containsAll(java.util.Collection<?> c)

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:

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[])

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

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

public char[] toArray(char[] a)
Description copied from interface: CharCollection
Returns a primitive type array containing the items of this collection.

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
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[])

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().
