Package	Description
org.mapstruct	MapStruct is a code generator which simplifies the implementation of mappings between Java bean types by generating mapping code at compile time, following a convention-over-configuration approach.
org.mapstruct.ap	This package and it sub-packages contain the implementation of the MapStruct annotation processor.
org.mapstruct.ap.internal.conversion	Provides built-in conversions between primitive and wrapper types, strings, dates etc.
org.mapstruct.ap.internal.model	Meta-model of mapper types, their methods, mappings between properties etc.
org.mapstruct.ap.internal.model.assignment	Meta-model of assignments.
org.mapstruct.ap.internal.model.beanmapping	helper classes used in BeanMappingMethod
org.mapstruct.ap.internal.model.common	Contains types which are shared between the intermediary mapping method model ("source model") and the mapper model.
org.mapstruct.ap.internal.model.dependency
org.mapstruct.ap.internal.model.presence
org.mapstruct.ap.internal.model.source	Intermediary representation of mapping methods as retrieved from via the annotation processing API.
org.mapstruct.ap.internal.model.source.builtin	Contains "built-in methods" which may be added as private methods to a generated mapper.
org.mapstruct.ap.internal.model.source.selector	Provides strategies for selecting a matching mapping or factory method when mapping from one attribute to another or instantiating the target type of a mapping method, respectively.
org.mapstruct.ap.internal.option	Provides access to the options passed to the annotation processor.
org.mapstruct.ap.internal.processor	Contains model processors which perform tasks such as retrieving mapping methods, creating a model representation and writing the model into Java source files.
org.mapstruct.ap.internal.processor.creation	Contains all helper classes for the MapperCreationProcessor
org.mapstruct.ap.internal.util	Several helper types dealing with collection types, option management etc.
org.mapstruct.ap.internal.util.accessor
org.mapstruct.ap.internal.version	Provides various version information
org.mapstruct.ap.internal.writer	Infrastructure for dealing with the FreeMarker template engine.
org.mapstruct.ap.spi	SPI (service provider interface) contracts to be implemented for advanced use cases.
org.mapstruct.ap.spi.util
org.mapstruct.control
org.mapstruct.factory	Provides the Mappers factory class for the retrieval of mapper instances if no explicit component model such as CDI is configured via Mapper.componentModel().
