Iterator
Iterator<T>
Available on all platformsAn
Iterator
is a structure that permits iteration over elements of typeT
.Any class with matching
hasNext()
andnext()
fields is considered anIterator
and can then be used e.g. infor
-loops. This makes it easy to implement custom iterators.See:
Properties
hasNext ():Bool
Returns false
if the iteration is complete, true
otherwise-
Usually iteration is considered to be complete if all elements of the underlying data structure were handled through calls to next()
- However, in custom iterators any logic may be used to determine the completion state-
next ():T
Returns the current item of the Iterator
and advances to the next one.
This method is not required to check hasNext()
first. A call to this method while hasNext()
is false
yields unspecified behavior.
On the other hand, iterators should not require a call to hasNext()
before the first call to next()
if an element is available.
