public abstract class StringElementHandlerBase
extends StAXContentHandlerBase

StAX handler for any element which just contains a string. This class collects the string data, and when it is complete, passes it to the (abstract) setStringValue method. Typical use of this class is as a base for a small (often anonymous) class which takes the string value and stores it in some variable.
