@zyberzebra I'm not fond of adding things such as trimLeading, replaceString or rather anything else special for the implementationName.

However, I would be open to providing an SPI, where we will pass the configured implementatioName and the name of the class and then this SPI can provide us with the name that should be used in the generated code.

Having said that, having something like InterfaceInventoryItemMapper as your interface and InventoryItemMapper as the impl class is a recipe for disaster. In my auto complete I would mostly use InventoryItemMapper.
