Examples with MetadataSource org.eclipse.persistence.jaxb.metadata.MetadataSource used on opensource projects

Example 1 with MetadataSource

use of org.eclipse.persistence.jaxb.metadata.MetadataSource in project eclipselink by eclipse-ee4j.

 * will load the eclipselink metadata model and unmarshal the Object. This assumes that the
 * Object represents the eclipselink-oxm.xml metadata file to be unmarshalled.

 * @param metadata assumed to be one of:  File, InputSource, InputStream, Reader, Source
