Package de.christofreichardt.diagnosis

Class TracerConfigNamespaceContextImpl

java.lang.Object

de.christofreichardt.diagnosis.TracerConfigNamespaceContextImpl

All Implemented Interfaces:

NamespaceContext

public class TracerConfigNamespaceContextImpl
extends Object
implements NamespaceContext

Since the TracerFactory uses XPath to access the XML configuration involving namespaces an implementation of the NamespaceContext interface is necessary. The implementation is simplified as only the namespace "http://www.christofreichardt.de/java/tracer" and the prefix "dns" will be considered.
