What?

Orika is a Java Bean mapping framework that recursively copies (among other capabilities) data from one object to another. It can be very useful when developing multi-layered applications.

Why?

Struggling with hand coded and reflection-based mappers? Orika can be used to simplify the process of mapping between one object layer and another.

Our ambition is to build a comprehensive, efficient and robust Java bean mapping solution. Orika focuses on automating as much as possible, while providing customization through configuration and extension where needed.

Orika enables the developer to : * Map complex and deeply structured objects * "Flatten" or "Expand" objects by mapping nested properties to top-level properties, and vice versa * Create mappers on-the-fly, and apply customizations to control some or all of the mapping * Create converters for complete control over the mapping of a specific set of objects anywhere in the object graph--by type, or even by specific property name * Handle proxies or enhanced objects (like those of Hibernate, or the various mock frameworks) * Apply bi-directional mapping with one configuration * Map to instances of an appropriate concrete class for a target abstract class or interface * Handle reverse mappings * Handle complex conventions beyond JavaBean specs.

How?

Orika uses byte code generation to create fast mappers with minimal overhead. Take a look at this simple performance test : http://bit.ly/pJ7n6t
