## Interface SQLActionVisitor

- All Known Implementing Classes:
    `DB2ActionBuilder`, `DerbyActionBuilder`, `FirebirdActionBuilder`, `H2ActionBuilder`, `IngresActionBuilder`, `JdbcActionBuilder`, `SQLServerActionBuilder`

      public interface SQLActionVisitor

  A factory interface to create standard SQLActions for a set of standard queries. Instances of SQLActionVisitor are passed by Cayenne to a Query in `Query.createSQLAction(SQLActionVisitor)`, allowing query to choose the action type and convert itself to a "standard" query if needed. Individual DbAdapters would provide special visitors, thus allowing for DB-dependent execution algorithms.

    1.2
