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.

| Modifier and Type | Method and Description |
|---|---|
| public Object | Returns: object for the given name, null if not foundproperty name propertyName, Map<String, ?> properties properties, SessionLog logger log)Check the provided map for an object with the given name. |
| public XMLEntityMappings | Returns: XMLEntityMappings - object representation of the EclipseLink-orm.xml for this repositoryOverrides org. Implements org. |
| public Reader | Returns: Reader - a InputStreamReader with data in the form of an EclipseLink-orm.xml- SessionLog used for status messages. log)This method returns a Reader for an EclipseLink-ORM.xml. |
| protected static URL | |
| public Map | getPropertyOverrides(Map<String, Object> properties, ClassLoader classLoader, SessionLog log)
Implements org. |
| public String | Returns: String - repository name to store in the XMLEntityMappings returned from getEntityMappingsUsed by getEntityMappings when creating the XMLEntityMappings as a way of describing where it was read from. |

|---|---|
| public XMLMetadataSource() Default constructor. | |
| getConfigPropertyLogDebug | back to summary |
|---|---|
| public Object getConfigPropertyLogDebug(final String propertyName, Map<String, ?> properties, SessionLog log) Check the provided map for an object with the given name. If that object is not available, check the System properties. Log the value returned if logging is enabled

| getEntityMappings | back to summary |
|---|---|
| public XMLEntityMappings getEntityMappings(Map<String, Object> properties, ClassLoader classLoader, SessionLog log) Overrides org. Implements org. 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.
| |
| getEntityMappingsReader | back to summary |
|---|---|
| public Reader getEntityMappingsReader(Map<String, Object> properties, ClassLoader classLoader, SessionLog log) This method 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.

| getFileURL | back to summary |
|---|---|
| protected static URL getFileURL(String fileName, ClassLoader classLoader, SessionLog log) throws IOException | |
| getPropertyOverrides | back to summary |
|---|---|
| public Map Implements org. PUBLIC: This method is responsible for returning additional persistence unit property overrides. It is called on initial deployment of the persistence unit and when the persistence unit is reloaded to allow customization of the persistence unit above and beyond what is packaged in the persistence.xml and what is code into the application. Important Note Although any property can be changed using this approach it is important that users of this feature ensure compatible configurations are supplied. As an example; overriding an application to use RESOURCE_LOCAL when it was coded to use JTA would result in changes not be written to the database. PersistenceUnitProperties.METADATA_SOURCE_PROPERTIES_FILE property will be used to get a file resource from the classloader. Properties are read from the file. If the property either not specified or contains an empty string then returns null.

| getRepositoryName | back to summary |
|---|---|
| public 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.
