reMap

Allows concise mapping definitions using method references, reducing boilerplate code compared to manual mapping, as shown in the demo snippet with reassign and replace operations.

Maps fields with equal names and types automatically, minimizing configuration effort for standard cases, which is core to its 'configure only differences' philosophy.

Validates mapping configuration at mapper instantiation, catching errors early by ensuring all fields are covered and no conflicts exist, as detailed in the validation section.

Handles custom functions, type mappings, and nested collections/maps, with examples in the cookbook for complex scenarios like property paths and collection conversions.

Provides an assertion API specifically for testing mapping specifications, making regression testing straightforward and reducing the need for custom unit tests.
