Class StaticWeaveClassTransformer

  • public class StaticWeaveClassTransformer
extends java.lang.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.
