Class AbstractFloatSet

java.lang.Object

java.util.AbstractCollection<Float>

it.unimi.dsi.fastutil.floats.AbstractFloatCollection

it.unimi.dsi.fastutil.floats.AbstractFloatSet

All Implemented Interfaces:

FloatCollection, FloatIterable, FloatSet, Cloneable, Iterable<Float>, Collection<Float>, Set<Float>

Direct Known Subclasses:

AbstractFloatSortedSet, FloatArraySet, FloatOpenCustomHashSet, FloatOpenHashBigSet, FloatOpenHashSet, FloatSets.Singleton

public abstract class AbstractFloatSet
extends AbstractFloatCollection
implements Cloneable, FloatSet

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

Note that the type-specific Set interface adds a type-specific remove() method, as it is no longer harmful for subclasses. Thus, concrete subclasses of this class must implement remove() (the rem() implementation of this class just delegates to remove()).

Method Summary

int	hashCode()	Returns a hash code for this set.
abstract FloatIterator	iterator()	Returns a type-specific iterator on the elements of this collection.
boolean	rem(float k)	Deprecated. Please use remove() instead.
boolean	remove(float k)	Removes an element from this set.

Method Details

iterator

public abstract FloatIterator iterator()

Description copied from interface: FloatCollection

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

Specified by:

iterator in interface Collection<Float>

Specified by:

iterator in interface FloatCollection

Specified by:

iterator in interface FloatIterable

Specified by:

iterator in interface FloatSet

Specified by:

iterator in interface Iterable<Float>

Specified by:

iterator in interface Set<Float>

Specified by:

iterator in class AbstractFloatCollection

Returns:

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

See Also:

• Iterable.iterator()

equals

public boolean equals(Object o)

Specified by:

equals in interface Collection<Float>

Specified by:

equals in interface Set<Float>

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns a hash code for this set. The hash code of a set is computed by summing the hash codes of its elements.

Specified by:

hashCode in interface Collection<Float>

Specified by:

hashCode in interface Set<Float>

Overrides:

hashCode in class Object

Returns:

a hash code for this set.

remove

public boolean remove(float k)

Removes an element from this set. Delegates to the type-specific rem() method implemented by type-specific abstract Collection superclass.

Specified by:

remove in interface FloatSet

See Also:

• Collection.remove(Object)

rem

@Deprecated
public boolean rem(float k)

Deprecated.

Please use remove() instead.

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(). Delegates to the type-specific remove() method specified in the type-specific Set interface.

Specified by:

rem in interface FloatCollection

Specified by:

rem in interface FloatSet

Overrides:

rem in class AbstractFloatCollection
