Example
scala
import com.sfxcode.sapphire.data.DataAdapter
case class Author(name: String)
case class Book(id: Long, title: String, pages: Int, author: Author)
// create DataAdapter for sample case class
val scalaBook = Book(1, "Programming In Scala", 852, Author("Martin Odersky"))
val book = DataAdapter[Book](scalaBook)
// value(key) and updateValue(key, newValue) are used for bean property access and modification
val title = book.value("title")
// "Programming In Scala"
val titleString:String = book.stringValue("title")
book.updateValue("title", "Programming In Scala 3.0")
// title is updated
val newTitle = book.value("title")
// "Programming In Scala 3.0"
// getValue and updateValue for underlying class by dot syntax
val authorName = book.value("author.name") // "Martin Odersky"
