I'm trying to implement the Apex Connector Framework, but when I try to create DataSource.Connection and DataSource.Provider classes, I get the following error when compiling:

"Type is not visible: DataSource.Connection"

This is the entirety of my sample DataSource.Connection class:

global class DBConnection extends DataSource.Connection {
	global DBConnection(DataSource.ConnectionParams connectionParams) {}
}

Does anyone know why I'm getting this error?  Thanks in advance for any help you can provide.

I'm trying to implement the Apex Connector Framework to hook up to an external database.  However, I'm getting the following error: "Type is not visible: DataSource.Connection."

Here is my code:
 

global class ChoozleDBConnection extends DataSource.Connection {
	global ChoozleDBConnection(DataSource.ConnectionParams connectionParams) {}
}

Thank you for any help you can provide!
