MapFilterIterator (Apache Jena)

java.lang.Object
- org.apache.jena.util.iterator.NiceIterator<X>
- - org.apache.jena.util.iterator.MapFilterIterator<T,X>

All Implemented Interfaces:

java.util.Iterator<X>, ClosableIterator<X>, ExtendedIterator<X>
```
public class MapFilterIterator<T,X>
extends NiceIterator<X>
implements ExtendedIterator<X>
```
A MapFilterIterator takes a MapFilter and an [Extended]Iterator and returns a new ExtendedIterator which delivers the sequence of all non-null elements MapFilter(X) for X from the base iterator.

`boolean`	`hasNext()`	Are there any more acceptable objects.

public MapFilterIterator(MapFilter<T,X> fl,
                         ExtendedIterator<T> e)
```
    Creates a sub-Iterator.
    
    Parameters:
    
    fl - An object is included if it is accepted by this Filter.
    
    e - The parent Iterator.
- Method Detail
  - hasNext
```
public boolean hasNext()
```
    Are there any more acceptable objects.
    
    Specified by:
    
    hasNext in interface java.util.Iterator<T>
    
    Overrides:
    
    hasNext in class NiceIterator<X>
    
    Returns:
    
    true if there is another acceptable object.
  - close
```
public void close()
```
    Description copied from class: NiceIterator
    
    default close: don't need to do anything.
    
    Specified by:
    
    close in interface ClosableIterator<T>
    
    Overrides:
    
    close in class NiceIterator<X>
  - remove
```
public void remove()
```
    remove's the member from the underlying Iterator; hasNext() may not be called between calls to next() and remove().
    
    Specified by:
    
    remove in interface java.util.Iterator<T>
    
    Overrides:
    
    remove in class NiceIterator<X>
  - next
```
public X next()
```
    The next acceptable object in the iterator.
    
    Specified by:
    
    next in interface java.util.Iterator<T>
    
    Overrides:
    
    next in class NiceIterator<X>
    
    Returns:
    
    The next acceptable object.
