Package 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.

See: Description

Enum Summary

Enum	Description
CollectionMappingStrategy	Strategy for propagating the value of collection-typed properties from source to target.
MappingInheritanceStrategy	Strategy for inheriting configurations given for methods of prototype mapping methods (declared on mapper config classes) to actual mapping methods declared on mappers referring to such config class via Mapper.config().
NullValueMappingStrategy	Strategy for dealing with null values passed to mapping methods.
ReportingPolicy	Policy for reporting issues occurring during the generation of a mapper implementation.

Annotation Types Summary

Annotation Type	Description
AfterMapping	Marks a method to be invoked at the end of a generated mapping method, right before the last return statement of the mapping method.
BeanMapping	Configures the mapping between two bean types.
BeforeMapping	Marks a method to be invoked at the beginning of a generated mapping method.
DecoratedWith	Specifies a decorator to be applied to a generated mapper, which e.g. can be used to amend mappings performed by generated mapping methods.
InheritConfiguration	Advises the code generator to apply the configuration (as given via Mapping, IterableMapping etc.)
InheritInverseConfiguration	Advises the code generator to apply all the Mappings from an inverse mapping method to the annotated method as well.
IterableMapping	Configures the mapping between two iterable types, e.g.
MapMapping	Configures the mapping between two map types, e.g.
Mapper	Marks an interface or abstract class as a mapper and activates the generation of a implementation of that type via MapStruct.
MapperConfig	Marks a class or interface as configuration source for generated mappers.
Mapping	Configures the mapping of one bean attribute or enum constant.
Mappings	Configures the mappings of several bean attributes.
MappingTarget	Declares a parameter of a mapping method to be the target of the mapping.
Qualifier	Declares an annotation type to be a qualifier.
TargetType	Declares a parameter of a custom mapping method to be populated with the target type of the mapping.

Package org.mapstruct Description

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. The generated code uses plain method invocations and thus is fast and type-safe.

This package contains several annotations which allow to configure how mapper interfaces are generated.
