MappingIterator (Jackson JSON Processor)

java.lang.Object
- org.codehaus.jackson.map.MappingIterator<T>

All Implemented Interfaces:

java.util.Iterator<T>
```
public class MappingIterator<T>
extends java.lang.Object
implements java.util.Iterator<T>
```
Iterator exposed by ObjectMapper when binding sequence of objects. Extension is done to allow more convenient exposing of IOException (which basic Iterator does not expose)

Since:

1.8
