gov.nist.secauto.metaschema.core.model.xml.ConstraintLoader

public class ConstraintLoader
extends AbstractLoader<IConstraintSet>

Provides methods to load a constraint set expressed in XML.

Loaded constraint instances are cached to avoid the need to load them for every use. Any constraint set imported is also loaded and cached automatically.
