Package org.glassfish.persistence.jpa.schemageneration

Class EclipseLinkSchemaGenerationProcessor

java.lang.Object
org.glassfish.persistence.jpa.schemageneration.EclipseLinkSchemaGenerationProcessor
All Implemented Interfaces:
SchemaGenerationProcessor
public class EclipseLinkSchemaGenerationProcessor extends Object implements SchemaGenerationProcessor
SchemaGenerationProcessor that handles schema generation while running against EclipseLink in pre JPA 2.1 mode For each persistence unit descriptors that is defined for an application create the ddl scripts. Additionally if the user has requested the tables to be created or dropped from the database complete that action too. These are the principles and expectations of the implementation. We don't want TopLink code to execute the DDLs, it should only generate them. So, we always set the *generation-mode* to *script* in the PUInfo object before passing it to createContainerEMF(). As a result TopLink never creates the actual tables, nor does it drop them. The DDLs are executed by our code based on user preference which considers inputs from persistence.xml and CLI. We set the TopLink property to DROP_AND_CREATE in that map because we want it to always generate both create- and dropDDL.jdbc files.
