All Implemented Interfaces:

RequestBoundaryDetector

public class XmlTailDetector

extends java.lang.Object

implements RequestBoundaryDetector

Detects the presence of the tail of an XML element in the Session bytes read in. This class can be used with a SessionReader if every client request is terminated by a character sequence that forms the tail of an XML element. If non-whitespace characters following the tail of the XML element are read into the passed in Session, then the requestCompleted method will fail (return false).
