Internal(built-in) classes that implement this interface can be used in a foreach construct and do not need to implement IteratorAggregate or Iterator.
The end iterator is pointing not to the last object, however, but to the first invalid object, or the object directly following the last one.
The better way is to employ an iterator, which is an object that implements either the Iterator or the ListIterator interface.
When the generator iterator resumes, it picks up where it left off(in contrast to functions which start fresh on every invocation).
We say that int* is a model of Input Iterator because int* provides all of the operations that are specified by the Input Iterator requirements.
When the asynchronous generator iterator effectively resumes with another awaitable returned by__anext__(), it picks up where it left off.
We describe the relationship between Input Iterator and Bidirectional Iterator by saying that Bidirectional Iterator is a refinement of Input Iterator.
Once the exception is thrown, we exit from try and move onto except, which will start the iterator over again.
To express a completely arbitrary lazy iterator in Java, you would need to write an Iterator that manually tracks its state.
The__iter()__ method acts similar, you can do operations(initializing, etc.), but must always return the iterator object itself.
Note: The returned iterator will be in an uninitialized state, and you must run the iterator.
When called initially, generator functions do not execute any of their code, instead returning a type of iterator called a Generator.
By far, the easiest way to do this is to employ an iterator, an object that implements either the Iterator or the Listiterator interface.
Single value containers: Each element is stored independently in the container and it is accessed directly or with an iterator.
This example illustrates the power of generators: if anything is an iterator, a generator can save the state of its iteration.
On each iteration, the iterator function is called to produce a new value, stopping when this new value is nil.
Note that it's not possible to use an iterator of promises to achieve the same result.
The Iterator provided in method iterator() is not guaranteed to traverse the elements of the PriorityBlockingQueue in any particular order.
Then we call filter to adapt that iterator into a new iterator that only contains elements for which the closure returns true.
The incoming method on TcpListener returns an iterator that gives us a sequence of streams(more specifically, streams of type TcpStream).
