Iterator

public interface Iterator

java.util.Iterator<E>

Known indirect subclasses CursorJoiner, EntityIterator, ListIterator<E>, PathIterator, PrimitiveIterator<T, T_CONS>, PrimitiveIterator.OfDouble, PrimitiveIterator.OfInt, PrimitiveIterator.OfLong, Scanner, TextUtils.SimpleStringSplitter CursorJoiner Does a join on two cursors using the specified columns.  EntityIterator A specialization of Iterator that allows iterating over a collection of Entity objects.  ListIterator<E> An iterator for lists that allows the programmer to traverse the list in either direction, modify the list during iteration, and obtain the iterator's current position in the list.  PathIterator PathIterator can be used to query a given Path object, to discover its operations and point values.  PrimitiveIterator<T, T_CONS> A base type for primitive specializations of Iterator.  PrimitiveIterator.OfDouble An Iterator specialized for double values.  PrimitiveIterator.OfInt An Iterator specialized for int values.  PrimitiveIterator.OfLong An Iterator specialized for long values.  Scanner A simple text scanner which can parse primitive types and strings using regular expressions.  TextUtils.SimpleStringSplitter A simple string splitter.

---

An iterator over a collection. Iterator takes the place of Enumeration in the Java Collections Framework. Iterators differ from enumerations in two ways:

• Iterators allow the caller to remove elements from the underlying collection during the iteration with well-defined semantics.
• Method names have been improved.

This interface is a member of the Java Collections Framework.

Summary

Public methods
default void	forEachRemaining(Consumer<? super E> action) Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
abstract boolean	hasNext() Returns true if the iteration has more elements.
abstract E	next() Returns the next element in the iteration.
default void	remove() Removes from the underlying collection the last element returned by this iterator (optional operation).
