How it works.

How mapping generator works

Mapping generator processing each @Mapper-annotated class individually. Generator perform next steps to create mapper implementation:

1. Collect defined mappings. Mapping is non-void method with single parameter. Mapping should be annotated with @Mapping or @Mappings annotation.

2. Generate mappings for dependencies. Combination of source and target types is unique identifier of generated mapping.

3. Generate implementation of collected and generated mappings.
