public class Main extends java.lang.Object
This is the controller for ij. It uses two parsers: one to grab the next statement, and another to see if it is an ij command, and if so execute it. If it is not an ij command, it is treated as a JSQL statement and executed against the current connection. ijParser controls the current connection, and so contains all of the state information for executing JSQL statements.This was written to facilitate a test harness for language functionality tests.

- Throws:
java.io.IOException
-
getMain
public Main getMain(LocalizedOutput out)
Get the right Main (according to the JDBC version.- Returns:
- The right main (according to the JDBC version).
-
getutilMain
public utilMain getutilMain(int numConnections, LocalizedOutput out)
Get the right utilMain (according to the JDBC version.- Returns:
- The right utilMain (according to the JDBC version).
-
getutilMain
public utilMain getutilMain(int numConnections, LocalizedOutput out, boolean loadSystemProperties)
