Examples of org.jboss.dna.cnd.CndImporter

org.jboss.dna.cnd.CndImporter
A class that imports the node types contained in a JCR Compact Node Definition (CND) file into graph content. The content is written using the graph structured defined by JCR and the " {@code nt:nodeType}", " {@code nt:propertyDefinition}", and " {@code nt:childNodeDefinition}" node types.
Although instances of this class never change their behavior and all processing is done in local contexts, {@link Destination}is not thread-safe and therefore this component may not be considered thread-safe.
