    • generateCacheResources

      public void generateCacheResources(Class<?>[] entities)
      Description copied from interface: ModelMapperSerializer
      A rich lifecycle method, calls will generate ModelMapper instances for the specified entities, serialize those ModelMappers, and persist those mappers to disk in a file entitled mappers.zip. The file is usually saved in the current application's source under the maven resources/cache directory structure. See ResourceProvider, and concrete implementations, for where and how the mappers.zip file is stored.

      A file called classes.zip is also created in the same location to hold any additional required classes that are needed to successfully deserialize the ModelMapper instances. These classes are generally injected into the target classloader upon deserialization (see ModelMapperSerializer.loadCacheResources(Class[])).
      Specified by:
      generateCacheResources in interface ModelMapperSerializer
      Parameters:
      entities - The entities from which to derive ModelMapper instances for serialization

    • generateCacheResources

      public void generateCacheResources(Class<?>[] entities, boolean hashShapes)
      Description copied from interface: ModelMapperSerializer
      A rich lifecycle method, calls will generate ModelMapper instances for the specified entities, serialize those ModelMappers, and persist those mappers to disk in a file entitled mappers.zip. The file is usually saved in the current application's source under the maven resources/cache directory structure. See ResourceProvider, and concrete implementations, for where and how the mappers.zip file is stored.

      A file called classes.zip is also created in the same location to hold any additional required classes that are needed to successfully deserialize the ModelMapper instances. These classes are generally injected into the target classloader upon deserialization (see ModelMapperSerializer.loadCacheResources(Class[])).
      Specified by:
      generateCacheResources in interface ModelMapperSerializer
      Parameters:
      entities - The entities from which to derive ModelMapper instances for serialization
      hashShapes - Whether or not the mapper cache should include a deep hash of the entity shape. This is useful if the cache archive is separated from the build process and can become stale. Stale cache entries will not match the entity shape at runtime and will not be accidentally included. This value should be false if the cache is always built during project compilation.

    • loadCacheResources

      public void loadCacheResources(Class<?>[] entities)
      Description copied from interface: ModelMapperSerializer
      A rich lifecycle method, calls will read ModelMapper serialized files from mappers.zip for the specified entities, deserialize those ModelMappers, and inject those mappers into cache upon application startup. classes.zip is also consulted and classes discovered there are injected into the current classloader prior to attempting deserialization. See ModelMapperSerializer.generateCacheResources(Class[]) for information on how mappers.zip and classes.zip originate.
      Specified by:
      loadCacheResources in interface ModelMapperSerializer
      Parameters:
      entities - The entities from which to deserialize ModelMapper instances and populate cache

    • serializeResources

      protected void serializeResources(Class<?>[] entities, boolean hashShape)
      Serialize the ModelMapper instances and required classes and put to mappers.zip and classes.zip by default. Alternatively, if broadleaf.modelmapper.cache.generate.useCacheInf is true, the serialized output will instead be put on the classpath at CACHE-INF/modelmapper.
      Parameters:
      entities - The entities for which ModelMapper instances are being created
      hashShape - see generateCacheResources(Class[], boolean).

    • appendAnyMissingClasses

      protected void appendAnyMissingClasses(String dumpDir, DynamicClassContext context)
      Review the dump dir and add any pertinent dynamic classes that may have been missed during class resolution at the time of serialization.
      Parameters:
      dumpDir - The location where ByteBuddy dumps dynamically created classes
      context - The context object containing the dynamic class registrations detected during serialization

    • getDumpFile

      protected com.broadleafcommerce.data.tracking.core.mapping.cache.DefaultModelMapperSerializer.ClassFile getDumpFile(String dumpDir, String[] files, String packageName, String simpleName)
      If the system detects a dynamic class required during serialization, retrieve it from the dump location used by ByteBuddy. See ModelMapperCacheProperties.getGenerate() #getDumpFile(String, String, String)} for configuration of the location of the dump directory.
      Parameters:
      dumpDir - The location where ByteBuddy dumps dynamically created classes
      packageName - The package name for the class file
      simpleName - The simple name of the class
      Returns:
      Stream to load the class file from disk

    • compileMappers
