class SourceCodeGenerator extends AbstractSourceCodeGenerator with OutputHelpers

A customizable code generator for working with Slick.

For usage information please see the corresponding part of the Slick documentation.

The implementation is structured into a small hierarchy of sub-generators responsible for different fragments of the complete output. The implementation of each sub-generator can be swapped out for a customized one by overriding the corresponding factory method. SourceCodeGenerator contains a factory method Table, which it uses to generate a sub-generator for each table. The sub-generator Table in turn contains sub-generators for Table classes, entity case classes, columns, key, indices, etc. Custom sub-generators can easily be added as well.

Within the sub-generators the relevant part of the Slick data model can be accessed to drive the code generation.

Of coures it makes sense to integrate this into your build process.
