Class StaticWeaveClassTransformer

java.lang.Object

oracle.toplink.essentials.internal.weaving.StaticWeaveClassTransformer

public class StaticWeaveClassTransformer
extends Object

Description: This class provides the implementation of class transformer by leveraging on the following existing APIs,

• PersistenceUnitProcessor.processORMetadata() - get class descriptor.
• PersistenceUnitProcessor.buildEntityList() - get entity classes lsit.
• TransformerFactory.createTransformerAndModifyProject - get class transformer.

Responsibilities:

• Create the classtransformer for each persistence unit individually and store them into the list.
• Provide class transfom method to perform weaving function.
