Class EditingIterator<T>

java.lang.Object
com.github.tommyettinger.ds.support.util.EditingIterator<T>
Type Parameters:
T - the type of items this can return, and the type the wrapped Iterator returns
All Implemented Interfaces:
Iterator<T>
public class EditingIterator<T> extends Object implements Iterator<T>
Wraps an Iterator so that it calls a function on each item it would otherwise return, and returns that function's result. If you need to return a different type than what the iterator returns, you can use an AlteringIterator. This has undefined behavior if any items the Iterator could return are modified during iteration.
You can change both the Iterator and editor at once using set(Iterator, ObjToSameFunction), and can also just change the Iterator with set(Iterator).
