      • contains

        public boolean contains​(float e)
        Description copied from interface: FloatContainer
        Lookup a given element in the container. This operation has no speed guarantees (may be linear with respect to the size of this container).
        Specified by:
        contains in interface FloatContainer
        Specified by:
        contains in interface FloatLookupContainer
        Returns:
        Returns true if this container has an element equal to e.

      • forEach

        public <T extends FloatProcedure> T forEach​(T procedure)
        Description copied from interface: FloatContainer
        Applies a procedure to all container elements. Returns the argument (any subclass of FloatProcedure. This lets the caller to call methods of the argument by chaining the call (even if the argument is an anonymous type) to retrieve computed values, for example (IntContainer): 
         int count = container.forEach(new IntProcedure() {
   int count; // this is a field declaration in an anonymous class.
 
   public void apply(int value) {
     count++;
   }
 }).count;
        Specified by:
        forEach in interface FloatContainer

      • forEach

        public <T extends FloatPredicate> T forEach​(T predicate)
        Description copied from interface: FloatContainer
        Applies a predicate to container elements as long, as the predicate returns true. The iteration is interrupted otherwise.
        Specified by:
        forEach in interface FloatContainer

      • iterator

        public java.util.Iterator<FloatCursor> iterator()
        Description copied from interface: FloatContainer
        Returns an iterator to a cursor traversing the collection. The order of traversal is not defined. More than one cursor may be active at a time. The behavior of iterators is undefined if structural changes are made to the underlying collection.

        The iterator is implemented as a cursor and it returns the same cursor instance on every call to Iterator.next() (to avoid boxing of primitive types). To read the current list's value (or index in the list) use the cursor's public fields. An example is shown below. 

         for (FloatCursor<float> c : container) {
   System.out.println("index=" + c.index + " value=" + c.value);
 }
        Specified by:
        iterator in interface FloatContainer
        Specified by:
        iterator in interface java.lang.Iterable<FloatCursor>

      • size

        public int size()
        Description copied from interface: FloatContainer
        Return the current number of elements in this container. The time for calculating the container's size may take O(n) time, although implementing classes should try to maintain the current size and return in constant time.
        Specified by:
        size in interface FloatContainer

      • removeAll

        public int removeAll​(FloatPredicate predicate)
        Description copied from interface: FloatCollection
        Removes all elements in this collection for which the given predicate returns true.
        Specified by:
        removeAll in interface FloatCollection
        Returns:
        Returns the number of removed elements.

      • removeAll

        public int removeAll​(float e)
        Description copied from interface: FloatCollection
        Removes all occurrences of e from this collection.
        Specified by:
        removeAll in interface FloatCollection
        Parameters:
        e - Element to be removed from this collection, if present.
        Returns:
        The number of removed elements as a result of this call.
