EmptyIntSet

public EmptyIntSet()

Method Details

getInstance

@ProtoFactory
public static EmptyIntSet getInstance()

contains

public boolean contains(int i)

Description copied from interface: IntSet

Whether this set contains the given int

Parameters:

i - the int to check

Returns:

if the set contains the int

containsAll

public boolean containsAll(IntSet set)

Description copied from interface: IntSet

Whether this set contains all ints in the given IntSet

Parameters:

set - the set to check if all are present

Returns:

if the set contains all the ints

size

public int size()

isEmpty

public boolean isEmpty()

contains

public boolean contains(Object o)

iterator

public PrimitiveIterator.OfInt iterator()

Description copied from interface: IntSet

A primtive iterator that allows iteration over the int values. This iterator supports removal if the set is modifiable.

Returns:

the iterator

toArray

public Object[] toArray()

toArray

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

containsAll

public boolean containsAll(Collection<?> c)

intStream

public IntStream intStream()

Description copied from interface: IntSet

A stream of ints representing the data in this set

Returns:

the stream

toBitSet

public byte[] toBitSet()

Description copied from interface: IntSet

Returns a byte array that has a bit set for each int in this set where each byte represents 8 numbers. That is if the ints 2, 5 and 9 are set this will return a byte array consisting of 2 bytes in little-endian representation of those values.

Depending upon the implementation this array may or may not have trailing bytes and may be condensed to save space.

Returns:

a byte array containing a little-endian representation of all the ints of this int set as bits

nextSetBit

public int nextSetBit(int fromIndex)

Description copied from interface: IntSet

Returns the next int in the set that is greater than or equal to the given value.

Parameters:

fromIndex - : inclusive index to start searching.

Returns:

the index of the next set bit, or -1 if there is no such bit

equals

public boolean equals(Object obj)

Specified by:

equals in interface Collection<Integer>

Specified by:

equals in interface Set<Integer>

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

add

public boolean add(int i)

Description copied from interface: IntSet

Adds the given int to this set and returns true if it was set or false if it was already present

Specified by:

add in interface IntSet

Parameters:

i - the int value to add

Returns:

whether this int was already present

set

public void set(int i)

Description copied from interface: IntSet

Adds or sets the int without returning whether it was previously set

Specified by:

set in interface IntSet

Parameters:

i - the value to make sure is in the set

remove

public boolean remove(int i)

Description copied from interface: IntSet

Removes, if present, the int from the set and returns if it was present or not

Specified by:

remove in interface IntSet

Parameters:

i - the int to remove

Returns:

whether the int was present in the set before it was removed

remove

public boolean remove(Object o)

Specified by:

remove in interface Collection<Integer>

Specified by:

remove in interface Set<Integer>

removeAll

public boolean removeAll(IntSet set)

Description copied from interface: IntSet

Removes all ints from this IntSet that are in the provided IntSet

Specified by:

removeAll in interface IntSet

Parameters:

set - the ints to remove from this IntSet

Returns:

if this set removed any ints

removeAll

public boolean removeAll(Collection<?> c)

Specified by:

removeAll in interface Collection<Integer>

Specified by:

removeAll in interface Set<Integer>

retainAll

public boolean retainAll(IntSet c)

Description copied from interface: IntSet

Modifies this set to remove all ints that are not present in the provided IntSet

Specified by:

retainAll in interface IntSet

Parameters:

c - the ints this set should kep

Returns:

if this set removed any ints

retainAll

public boolean retainAll(Collection<?> c)

Specified by:

retainAll in interface Collection<Integer>

Specified by:

retainAll in interface Set<Integer>

add

public boolean add(Integer integer)

Specified by:

add in interface Collection<Integer>

Specified by:

add in interface Set<Integer>

addAll

public boolean addAll(IntSet set)

Description copied from interface: IntSet

Adds all ints from the provided set into this one

Specified by:

addAll in interface IntSet

Parameters:

set - the set of ints to add

Returns:

if this set has a new int in it

addAll

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

Specified by:

addAll in interface Collection<Integer>

Specified by:

addAll in interface Set<Integer>

clear

public void clear()

Specified by:

clear in interface Collection<Integer>

Specified by:

clear in interface Set<Integer>

removeIf

public boolean removeIf(Predicate<? super Integer> filter)

Specified by:

removeIf in interface Collection<Integer>

removeIf

public boolean removeIf(IntPredicate filter)

Description copied from interface: IntSet

Removes all the ints of this set that satisfy the given predicate. Errors or runtime exceptions thrown during iteration or by the predicate are relayed to the caller. The default implementation traverses all elements of the collection using its IntSet.iterator(). Each matching element is removed using Iterator.remove(). If the collection's iterator does not support removal then an UnsupportedOperationException will be thrown on the first matching element.

Specified by:

removeIf in interface IntSet

Parameters:

filter - a predicate which returns true for ints to be removed

Returns:

true if any ints were removed
