Examples of NamespaceInfo

org.apache.hadoop.hdfs.server.protocol.NamespaceInfo
NamespaceInfo is returned by the name-node in reply to a data-node handshake.
org.eclipse.wst.xml.core.internal.contentmodel.util.NamespaceInfo
org.geoserver.catalog.NamespaceInfo
Application schema namespace. @author Justin Deoliveira, The Open Planning Project
org.openquark.util.xml.NamespaceInfo
This is a simple container class to encapsulate a namespace URI and its corresponding prefix. @author Edward Lam
org.vfny.geoserver.global.NameSpaceInfo
NameSpaceInfo purpose.
A representation of a namespace for the Geoserver application.

NameSpaceInfo ns = new NameSpaceInfo(dto); System.out.println(ns.getPrefix() + ns.getUri());
