Interface SQLActionVisitor

All Known Implementing Classes:

DB2ActionBuilder, DerbyActionBuilder, FirebirdActionBuilder, FrontBaseActionBuilder, 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.
