Class LongSets.Singleton

  • All Implemented Interfaces:
    LongCollection, LongIterable, LongSet, java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<java.lang.Long>, java.util.Collection<java.lang.Long>, java.util.Set<java.lang.Long>
    Direct Known Subclasses:
    LongSortedSets.Singleton
    Enclosing class:
    LongSets

    public static class LongSets.Singleton
    extends AbstractLongSet
    implements java.io.Serializable, java.lang.Cloneable
    An immutable class representing a type-specific singleton set.

    This class may be useful to implement your own in case you subclass a type-specific set.

    • Method Detail

      • contains

        public boolean contains​(long k)
        Description copied from class: AbstractLongCollection
        Returns true if this collection contains the specified element.

        This implementation iterates over the elements in the collection, looking for the specified element.

        Specified by:
        contains in interface LongCollection
        Overrides:
        contains in class AbstractLongCollection
        See Also:
        Collection.contains(Object)
      • remove

        public boolean remove​(long k)
        Description copied from class: AbstractLongSet
        Removes an element from this set.

        Note that the corresponding method of a type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface. Delegates to the type-specific rem() method implemented by type-specific abstract Collection superclass.

        Specified by:
        remove in interface LongSet
        Overrides:
        remove in class AbstractLongSet
        See Also:
        Collection.remove(Object)
      • iterator

        public LongListIterator iterator()
        Description copied from interface: LongCollection
        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 java.util.Collection<java.lang.Long>
        Specified by:
        iterator in interface java.lang.Iterable<java.lang.Long>
        Specified by:
        iterator in interface LongCollection
        Specified by:
        iterator in interface LongIterable
        Specified by:
        iterator in interface LongSet
        Specified by:
        iterator in interface java.util.Set<java.lang.Long>
        Specified by:
        iterator in class AbstractLongSet
        Returns:
        a type-specific iterator on the elements of this collection.

        public boolean addAll​(java.util.Collection<? extends java.lang.Long> c)
        Description copied from class: AbstractLongCollection

        This implementation delegates to the type-specific version if given a type-specific collection, otherwise is uses the implementation from AbstractCollection.
