javax.xml.transform.Result,Receiver
public class ContentDetector extends ProxyReceiver
A ContentDetector is a filter that can be added to a Receiver pipeline to note whether the current element node has children. It delays sending the startElement() event to the next Receiver in the pipeline until it is known whether the start tag is followed by children, or is followed immediately by an end tag. It then passes this information to subsequent filters in the pipeline by use of property flags.
