Interface DatabaseConnectionProxyFactory

All Known Implementing Classes:

ReflectionDatabaseConnectionProxyFactory

public interface DatabaseConnectionProxyFactory

Defines a class that creates connection proxies. This can be set on the JdbcConnectionSource or AndroidConnectionSource using the setDatabaseConnectionProxyFactory(...) static method on each class.

Typically you create a subclass of DatabaseConnectionProxy and override the methods that you want to wrap for logging, monitoring, or other reason. Something like:

 private static class MyConnectionProxy extends DatabaseConnectionProxy {
        public ConnectionProxy(DatabaseConnection conn) {
                super(conn);
        }
        @Override
        public int insert(String statement, Object[] args, FieldType[] argfieldTypes, GeneratedKeyHolder keyHolder)
                        throws SQLException {
                // do something here to the arguments or write to a log or something
                return super.insert(statement, args, argfieldTypes, keyHolder);
        }
 }
 

Then define your own factory which constructs instances of your proxy object. For example:

 JdbcConnectionSource.setDatabaseConnectionProxyFactory(new DatabaseConnectionProxyFactory() {
        public DatabaseConnection createProxy(DatabaseConnection realConnection) {
                return new MyConnectionProxy(realConnection);
        }
 });
 

You can also use the ReflectionDatabaseConnectionProxyFactory which takes a class and constructs your proxy subclass using reflection.

To see a working example of the connection proxy, see the DatabaseConnectionProxyFactoryTest.
