      • contains

        public boolean contains​(KType e)
        Description copied from interface: ObjectContainer
        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 ObjectContainer<KType>
        Specified by:
        contains in interface ObjectLookupContainer<KType>
        Returns:
        Returns true if this container has an element equal to e.
      • forEach

        public <T extends ObjectProcedure<? super KType>> T forEach​(T procedure)
        Description copied from interface: ObjectContainer
        Applies a procedure to all container elements. Returns the argument (any subclass of ObjectProcedure. 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 ObjectContainer<KType>
      • forEach

        public <T extends ObjectPredicate<? super KType>> T forEach​(T predicate)
        Description copied from interface: ObjectContainer
        Applies a predicate to container elements as long, as the predicate returns true. The iteration is interrupted otherwise.
        Specified by:
        forEach in interface ObjectContainer<KType>
      • iterator

        public java.util.Iterator<ObjectCursor<KType>> iterator()
        Description copied from interface: ObjectContainer
        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 (ObjectCursor<Object> c : container) {
           System.out.println("index=" + c.index + " value=" + c.value);
         }
         
        Specified by:
        iterator in interface java.lang.Iterable<ObjectCursor<KType>>
        Specified by:
        iterator in interface ObjectContainer<KType>
      • size

        public int size()
        Description copied from interface: ObjectContainer
        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 ObjectContainer<KType>
      • removeAll

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