java.lang.Object
- net.sourceforge.pmd.util.IteratorUtil.AbstractIterator<T>

Type Parameters:

T - the type of the elements

All Implemented Interfaces:

Iterator<T>

Direct Known Subclasses:

IteratorUtil.AbstractPausingIterator

Enclosing class:

IteratorUtil
```
public abstract static class IteratorUtil.AbstractIterator<T>
extends Object
implements Iterator<T>
```
Note, that this iterator doesn't support the remove operation.

- Method Detail
  - hasNext
```
public boolean hasNext()
```
    Specified by:
    
    hasNext in interface Iterator<T>
  - next
```
public T next()
```
    Specified by:
    
    next in interface Iterator<T>
  - setNext
```
protected final void setNext(T t)
```
  - done
```
protected final void done()
```
  - computeNext
```
protected abstract void computeNext()
```
    Compute the next element. Implementations must call either done() or setNext(Object) exactly once.
  - remove
```
public final void remove()
```
    This implementation throws an instance of UnsupportedOperationException and performs no other action.
    
    Specified by:
    
    remove in interface Iterator<T>
    
    Throws:
    
    UnsupportedOperationException - always, as the remove operation is not supported by this iterator
