Class XmlMetaDataEntityResolver

java.lang.Object

org.datanucleus.metadata.xml.XmlMetaDataEntityResolver

All Implemented Interfaces:

EntityResolver

public class XmlMetaDataEntityResolver
extends Object
implements EntityResolver

Implementation of an entity resolver for XML MetaData files. Supports a series of internally supported public or system identities. Note that this applies to ALL types of XML MetaData (persistence.xml, JDO package.jdo, JDO package.orm, JDO package.jdoquery, JPA/Jakarta orm.xml). We could, potentially, separate these different types of MetaData XML file, and hence split up the entities based on the handler, but not considered a priority currently.
