Class CollectionsP.RemoveFirstAndLastIterator<T>

java.lang.Object
org.plumelib.util.CollectionsP.RemoveFirstAndLastIterator<T>
Type Parameters:
T - the type of elements of the iterator
All Implemented Interfaces:
Iterator<T>
Enclosing class:
CollectionsP
public static final class CollectionsP.RemoveFirstAndLastIterator<T> extends Object implements Iterator<T>
Returns an iterator just like its argument, except that the first and last elements are removed. They can be accessed via the getFirst() and getLast() methods.

  • Method Details

    • hasNext

      public boolean hasNext(@GuardSatisfied CollectionsP.RemoveFirstAndLastIterator<T> this)
      Specified by:
      hasNext in interface Iterator<T>

    • next

      public T next(@GuardSatisfied CollectionsP.RemoveFirstAndLastIterator<T> this)
      Specified by:
      next in interface Iterator<T>

    • getFirst

      @Pure public T getFirst()
      Returns the first element of the iterator that was used to construct this. This value is not part of this iterator (unless the original iterator would have returned it multiple times).
      Returns:
      the first element of the iterator that was used to construct this

    • getLast

      @Pure public T getLast()
      Returns the last element of the iterator that was used to construct this. This value is not part of this iterator (unless the original iterator would have returned it multiple times).

      Throws an error unless the RemoveFirstAndLastIterator has already been iterated all the way to its end (so the delegate is pointing to the last element).

      Returns:
      the last element of the iterator that was used to construct this

    • remove

      public void remove(@GuardSatisfied CollectionsP.RemoveFirstAndLastIterator<T> this)
      Specified by:
      remove in interface Iterator<T>
