Class MultiIterator<T>

java.lang.Object
jadex.collection.MultiIterator<T>
All Implemented Interfaces:
Iterator<T>
public class MultiIterator<T> extends Object implements Iterator<T>
Iterator that operates over multiple collections.

  • Field Details

    • its

      protected List<Iterator<T>> its
      The data collections.

    • collcnt

      protected int collcnt
      The counter for the collection.

    • curit

      protected Iterator<T> curit
      The current iterator.

  • Constructor Details

    • MultiIterator

      public MultiIterator()
      Create a new MultiCollectionIterator.

  • Method Details

    • addIterator

      public void addIterator(Iterator<T> it)
      Add a collection.
      Parameters:
      coll - The collection.

    • hasNext

      public boolean hasNext()
      Returns true if the iteration has more elements. (In other words, returns true if next() would return an element rather than throwing an exception.)
      Specified by:
      hasNext in interface Iterator<T>
      Returns:
      true if the iteration has more elements

    • next

      public T next()
      Returns the next element in the iteration.
      Specified by:
      next in interface Iterator<T>
      Returns:
      the next element in the iteration
      Throws:
      NoSuchElementException - if the iteration has no more elements

    • remove

      public void remove()
      Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to next(). The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.
      Specified by:
      remove in interface Iterator<T>
      Throws:
      UnsupportedOperationException - if the remove operation is not supported by this iterator
      IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method

    • getCurrentIterator

      protected Iterator<T> getCurrentIterator()
      Get the current iterator.
