Class SchemaAnnotationsAccess

java.lang.Object

com.darkcollective.relix.semantic.internal.SchemaAnnotationsAccess

public final class SchemaAnnotationsAccess
extends Object

How the analyser records a node's schema in a SchemaAnnotations.

SchemaAnnotations is published and a caller only reads it, so its writer is not public there. The analyser lives in this package, so the published class hands its writer over when it loads and the analyser writes through here. The jar does not export this package, so the writer stays the engine's.
