      Deprecated.
      Please use the corresponding type-specific method instead.
      boolean addAll​(DoubleCollection c)
      Adds all elements of the given type-specific collection to this collection.
      boolean contains​(double k)
      Returns true if this collection contains the specified element.

      • iterator

        public abstract DoubleIterator iterator()
        Description copied from interface: DoubleCollection
        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.Double>
        Specified by:
        iterator in interface DoubleCollection
        Specified by:
        iterator in interface DoubleIterable
        Specified by:
        iterator in interface java.lang.Iterable<java.lang.Double>
        Specified by:
        iterator in class java.util.AbstractCollection<java.lang.Double>
        Returns:
        a type-specific iterator on the elements of this collection.

      • add

        public boolean add​(double k)
        Ensures that this collection contains the specified element (optional operation).

        This implementation always throws an UnsupportedOperationException.

        Specified by:
        add in interface DoubleCollection
        See Also:
        Collection.add(Object)
      • contains

        public boolean contains​(double k)
        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 DoubleCollection
        See Also:
        Collection.contains(Object)
      • rem

        public boolean rem​(double k)
        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().

        This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.

      • toArray

        public double[] toArray​(double[] a)
        Description copied from interface: DoubleCollection
        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 DoubleCollection
        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.

        Collection.toArray(Object[])
