Class JsonKeyIterator

java.lang.Object

de.geeksfactory.opacclient.utils.JsonKeyIterator

All Implemented Interfaces:

java.util.Iterator<java.lang.String>

public class JsonKeyIterator
extends java.lang.Object
implements java.util.Iterator<java.lang.String>

This Iterator takes a JSONObject and iterates over its keys. In contrast to JSONObject.keys(), this Iterator will always return Strings instead of generic Objects, so it prevents unchecked casts. If the value returned from JSONObject.keys()'s Iterator.next() method is no String (which probably cannot happen), the next() method will throw a IllegalArgumentException.
