Method Details

remove

public boolean remove(char k)

Description copied from interface: CharSet

Removes an element from this set.

Specified by:

remove in interface CharSet

See Also:

• Collection.remove(Object)

rem

@Deprecated
public boolean rem(char k)

Deprecated.

Description copied from interface: CharCollection

Removes a single instance of the specified element from this collection, if it is present (optional operation).

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

Specified by:

rem in interface CharSet

See Also:

• Collection.remove(Object)

add

public boolean add(char k)

Description copied from interface: CharCollection

Ensures that this collection contains the specified element (optional operation).

Specified by:

add in interface CharCollection

See Also:

• Collection.add(Object)

contains

public boolean contains(char k)

Description copied from interface: CharCollection

Returns true if this collection contains the specified element.

Specified by:

contains in interface CharCollection

See Also:

• Collection.contains(Object)

size

public int size()

Specified by:

size in interface Collection<Character>

isEmpty

public boolean isEmpty()

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()

toArray

public Object[] toArray()

Specified by:

toArray in interface Collection<Character>

toCharArray

@Deprecated
public char[] toCharArray(char[] a)

Deprecated.

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:

toCharArray in interface CharCollection

Parameters:

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

a primitive type array containing the items of this collection.

See Also:

toArray

public char[] toArray(char[] a)

Description copied from interface: CharCollection

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

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[])

addAll

public boolean addAll(CharCollection c)

Description copied from interface: CharCollection

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

Specified by:

addAll in interface CharCollection

Parameters:

Description copied from interface: CharCollection

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:

intIterator

public IntIterator intIterator()

Description copied from interface: CharCollection

Returns a widened primitive iterator on the elements of this collection.

This method is provided for the purpose of APIs that expect only the JDK's primitive iterators, of which there are only int, long, and double.

WARNING: This is not the same as converting the source to a sequence of code points. This returned instance literally performs (int)(charValue) casts. Surrogate pairs will be left as separate elements instead of combined into a single element with the code point it represents. See Character for more discussion on code points, char values, and surrogate pairs.

Specified by:

intIterator in interface CharCollection

Specified by:

intIterator in interface CharIterable

Returns:

a widened primitive iterator on the elements of this collection.

intSpliterator
