Class ToStringIterator

java.lang.Object

org.apache.stanbol.entityhub.servicesapi.util.ToStringIterator

All Implemented Interfaces:

Iterator<String>

public class ToStringIterator
extends Object
implements Iterator<String>

Implementation of an Iterator over String values, that uses the Object.toString() on elements of the parent Iterator for the conversion.

This Implementation does not use AdaptingIterators implementation, because the Object.toString() method can be used to create a string representation for every object and therefore there is no need for the filtering functionality provided by the AdaptingIterator.
