Method Detail

size

public int size()
Specified by:
size in interface Collection

isEmpty

public boolean isEmpty()
Specified by:
isEmpty in interface Collection

contains

public boolean contains(char o)
Specified by:
contains in interface CharCollection
See Also:
Collection.contains(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
Builds a primitive type array containing the items of this collection.

Specified by:
toCharArray in interface CharCollection
Parameters:
a - if this array is big enough, it will be used to store the collection.
Returns:
a primitive type array containing the items of this collection.
See Also:
Collection.toArray(Object[])

iterator

public Iterator iterator()
Specified by:
iterator in interface Collection

charIterator

public CharIterator charIterator()
Description copied from interface: CharCollection
Returns a type-specific iterator on the collection.

The iterator returned by the Collection.iterator() method and by this method are identical; however, using this method you can save a type casting.

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

add

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

remove

public boolean remove(Object ok)
Specified by:

Specified by:
containsAll in interface Collection

removeAll

public boolean removeAll(Collection c)
Specified by:
removeAll in interface Collection

retainAll

public boolean retainAll(Collection c)
Specified by:
retainAll in interface Collection

addAll

public boolean addAll(CharCollection c)
Specified by:
addAll in interface CharCollection
See Also:

containsAll

public boolean containsAll(CharCollection c)
Specified by:
containsAll in interface CharCollection
See Also:
Collection.containsAll(Collection)

removeAll

public boolean removeAll(CharCollection c)
Specified by:
removeAll in interface CharCollection
See Also:
Collection.removeAll(Collection)

retainAll

public boolean retainAll(CharCollection c)
Specified by:
retainAll in interface CharCollection

toArray

public Object[] toArray()
Specified by:
toArray in interface Collection

toArray

public Object[] toArray(Object[] a)
Specified by:
toArray in interface Collection

toArray

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

Specified by:
toArray in interface CharCollection
Parameters:
a - if this array is big enough, it will be used to store the collection.
