Method Summary

Method Detail

remove

default void remove()

Removes from the underlying collection the last element returned by this iterator. This method can be called only once per call to DIterator.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. The default implementation throws an instance of UnsupportedOperationException and performs no other action.

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

forEachRemaining

default void forEachRemaining(DoubleConsumer action)

Performs the given action for each remaining element until all elements have been processed or the action throws an exception. Actions are performed in the order of iteration. Exceptions thrown by the action are relayed to the caller.

The default implementation behaves as if:

 
     while (hasNext())
         action.accept(next());
 
 

Parameters:

action - The action to be performed for each element

Throws:

NullPointerException - if the specified action is null
