All Implemented Interfaces:

StAXContentHandler

public abstract class BooleanElementHandlerBase
extends StAXContentHandlerBase

StAX handler for any element which just contains a string representation of an boolean.

This calss collects the string data, and when it is complete, passes it to the (abstract) setBooleanValue method. Typical use of this class is as a base for a small (often anonymous) class which takes the boolean value and stores it in some variable.
