Type Members

1.  case class ColumnDescription(name: String, typeName: String, jdbcType: Int, tableName: String) extends Product with Serializable
2.  case class DatabaseMetadata(dbConnection: DbConnection) extends Product with Serializable

   Holds metadata (tables, column types, primary and foreign keys) for a DbConnection

3.  case class ForeignKey(name: String, primaryColumn: String, primaryTable: String, foreignColumn: String) extends Product with Serializable
4.  case class GuessedMetadata(standardDbMetadata: DatabaseMetadata, skippedTables: Set[String] = Set.empty, skippedLinks: Set[Link] = Set.empty, guessMissingForeignKeys: Boolean = true) extends Product with Serializable
5.  case class Link(from: String, to: String) extends Product with Serializable

   from and to are regular expressions used to filter links.

6.  case class PolymorphicColumnPair(table: String, idColumn: ColumnDescription, typeColumn: ColumnDescription) extends Product with Serializable

   A polymorphic link is a concept sometimes used in Ruby on Rails applications.

   A polymorphic link is a concept sometimes used in Ruby on Rails applications. It is similar to a foreign key, but the foreign table has an extra column to indicate which primary table is concerned for a given row.

   Ex:

   • primary tables Buyer and Store
   • polymorphic foreign table Location, with columns
     • locationable_id (matches with buyer.id or store.id)
     • location_type (either buyer or store)
7.  case class TableMetaData(tableName: String, primaryKeyColumns: Seq[String], foreignKeys: Seq[ForeignKey], columns: Seq[ColumnDescription]) extends Product with Serializable

   Holds metadata (column types, primary and foreign keys) for a single table.
