Enclosing class:
BooleanIterators
public static class BooleanIterators.EmptyIterator

  • Method Details

    • hasNext

      public boolean hasNext()
      Specified by:
      hasNext in interface java.util.Iterator<java.lang.Boolean>
      Specified by:
      hasNext in interface java.util.ListIterator<java.lang.Boolean>

    • hasPrevious

      public boolean hasPrevious()
      Description copied from interface: BidirectionalIterator
      Returns whether there is a previous element.
      Specified by:
      hasPrevious in interface BidirectionalIterator<java.lang.Boolean>
      Specified by:
      hasPrevious in interface java.util.ListIterator<java.lang.Boolean>
      Returns:
      whether there is a previous element.
      See Also:
      ListIterator.hasPrevious()

    • nextBoolean

      public boolean nextBoolean()
      Description copied from interface: BooleanIterator
      Returns the next element as a primitive type.
      Specified by:
      nextBoolean in interface BooleanIterator
      Returns:
      the next element in the iteration.
      See Also:
      Iterator.next()

    • previousBoolean

      public boolean previousBoolean()
      Description copied from interface: BooleanBidirectionalIterator
      Returns the previous element as a primitive type.
      Specified by:
      previousBoolean in interface BooleanBidirectionalIterator
      Returns:
      the previous element in the iteration.
      See Also:
      ListIterator.previous()

    • nextIndex

      public int nextIndex()
      Specified by:
      nextIndex in interface java.util.ListIterator<java.lang.Boolean>

    • previousIndex

      public int previousIndex()
      Specified by:
      previousIndex in interface java.util.ListIterator<java.lang.Boolean>

    • skip

      public int skip​(int n)
      Description copied from interface: BooleanBidirectionalIterator
      Skips the given number of elements.

      The effect of this call is exactly the same as that of calling BooleanIterator.next() for n times (possibly stopping if Iterator.hasNext() becomes false).

      Specified by:
      skip in interface BooleanBidirectionalIterator
      Specified by:
      skip in interface BooleanIterator
      Specified by:
      skip in interface ObjectBidirectionalIterator<java.lang.Boolean>
      Specified by:
      skip in interface ObjectIterator<java.lang.Boolean>
      Parameters:
      n - the number of elements to skip.
      Returns:
      the number of elements actually skipped.
      See Also:
      Iterator.next()

    • back

      public int back​(int n)
      Description copied from interface: BooleanBidirectionalIterator
      Moves back for the given number of elements.

      The effect of this call is exactly the same as that of calling BooleanBidirectionalIterator.previous() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

      Specified by:
      back in interface BooleanBidirectionalIterator
      Specified by:
      back in interface ObjectBidirectionalIterator<java.lang.Boolean>
      Parameters:
      n - the number of elements to skip back.
      Returns:
      the number of elements actually skipped.
      See Also:
      BooleanBidirectionalIterator.previous()

    • forEachRemaining

      public void forEachRemaining​(BooleanConsumer action)
      Description copied from interface: BooleanIterator
      Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
      Specified by:
      forEachRemaining in interface BooleanIterator
      Specified by:
      forEachRemaining in interface java.util.PrimitiveIterator<java.lang.Boolean,​BooleanConsumer>
      Parameters:
      action - the action to be performed for each element.
      See Also:
      Iterator.forEachRemaining(java.util.function.Consumer)

    • forEachRemaining

      @Deprecated public void forEachRemaining​(java.util.function.Consumer<? super java.lang.Boolean> action)
      Deprecated.
      Description copied from interface: BooleanIterator
      Specified by:
      forEachRemaining in interface BooleanIterator
      Specified by:
