Class XMLMetadataSource
java.lang.Object
org.eclipse.persistence.jpa.metadata.MetadataSourceAdapter
org.eclipse.persistence.jpa.metadata.XMLMetadataSource
- All Implemented Interfaces:
- MetadataSource
-
public class XMLMetadataSource
- extends MetadataSourceAdapter
Purpose: Support reading metadata for a persistence unit in an XML format from a URL and if the property is undefined, it will look for a file.

XMLMetadataSource
public XMLMetadataSource()
getEntityMappingsReader
public java.io.Reader getEntityMappingsReader(java.util.Map<java.lang.String,java.lang.Object> properties,
java.lang.ClassLoader classLoader,
SessionLog log)
- This class returns a Reader for an EclipseLink-ORM.xml. It will use the PersistenceUnitProperties.METADATA_SOURCE_XML_URL property if available to create an InputStreamReader from a URL, and if not available, use the PersistenceUnitProperties.METADATA_SOURCE_XML_FILE property will be used to get a file resource from the classloader. It will throw a ValidationException if no reader can be returned.
-
- Parameters:
properties
-
classLoader
-
log
- - SessionLog used for status messages.
- Returns:
- Reader - a InputStreamReader with data in the form of an EclipseLink-orm.xml

getEntityMappings
public org.eclipse.persistence.internal.jpa.metadata.xml.XMLEntityMappings getEntityMappings(java.util.Map<java.lang.String,java.lang.Object> properties,
java.lang.ClassLoader classLoader,
SessionLog log)
- This method is responsible for returning the object representation of the MetadataSource. This implementation makes a call to getEntityMappingsReader to get a Reader which is passed to an XMLUnmarshaller, and closes the reader in a finally block.
-
- Specified by:
getEntityMappings
in interface MetadataSource
- Overrides:
getEntityMappings
in class MetadataSourceAdapter
-
- Returns:
- XMLEntityMappings - object representation of the EclipseLink-orm.xml for this repository
getRepositoryName
public java.lang.String getRepositoryName()
- Used by getEntityMappings when creating the XMLEntityMappings as a way of describing where it was read from. Currently returns the current class's simple name.
-
- Returns:
- String - repository name to store in the XMLEntityMappings returned from getEntityMappings
