All Implemented Interfaces:

EffectiveModelContextProvider

public final class DataSchemaContextTree
extends AbstractEffectiveModelContextProvider

Semantic tree binding a EffectiveModelContext 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.
