Class DataSchemaContextTree

java.lang.Object

org.opendaylight.yangtools.yang.data.util.DataSchemaContextTree

public final class DataSchemaContextTree
extends Object

Semantic tree binding a SchemaContext to a NormalizedNode tree. Since the layout of the schema and data has differences, the mapping is not trivial -- which is where this class comes in.
