PgCompositeMapper

interface PgCompositeMapper<T : Any>

Interface for manual (non-reflective) mapping of a data class to/from a Map. Used by PgComposite to bypass reflection-based mapping and improve performance.

This is an alternative to reflection that can be manually implemented or generated by external tools.
