ExpandingNodeIterator (JCS Classic Connector Module 8.6.0-7 API)

java.lang.Object
- com.saperion.common.lang.iterator.ExpandingNodeIterator<T>

Type Parameters:

T - type of objects to iterate

All Implemented Interfaces:

java.util.Iterator<T>
```
public final class ExpandingNodeIterator<T>
extends java.lang.Object
implements java.util.Iterator<T>
```
An ExpandingNodeIterator iterates through all nodes of a virtual two level data structure.

It iterates through the objects of the specified main iterator. After returning the main-level object a call to the specified IteratorResolver is executed to get an iterator for the optional virtual sub elements. If such an iterator is found, all the sub elements will be iterated through after the main object.

Then, the main iterator will step to the next main object and its sub elements and so on.

Iterator.remove() is not supported.
