Expected behavior

Hi everyone, I want to use default name strategy if schema is public and default + special name strategy if schema is provided:

class SchemaNamingStrategy(schema: String) extends NamingStrategy {
  override def table(s: String): String   = s"$schema.$s"
  override def default(s: String): String = s
}

private val schemaNamingStrategy = employeeSchema match {
    case "public" =>
      defaultNamingStrategy  // snake case, single naming strategy

    case schema =>
      NamingStrategy(defaultNamingStrategy, new SchemaNamingStrategy(schema))  // composite naming strategy of type CompositeNamingStrategy2
}

CompositeNamingStrategy extends NamingStrategy just like SnakeCase do so schemaNamingStrategy should be of type NamingStrategy.

Actual behavior

Workaround

I use SchemaNamingStrategy with default schema to produce the CompositeNamingStrategy2 at every output.

private val schemaNamingStrategy = employeeSchema match {
    case "public" =>
      NamingStrategy(defaultNamingStrategy, new SchemaNamingStrategy("public"))

    case schema =>
      NamingStrategy(defaultNamingStrategy, new SchemaNamingStrategy(schema)) 
  }
