Direct Known Subclasses:

StartConnection

public class JavaToLisp

extends Object

This is a tool for connecting to Lisp through JLinker. Use the connectToLisp() method to make the connection. Then other methods such as runInLisp and loadFile may be used. The main method will pop up a dialog box into which expressions may be typed and evaluated. Created: Fri Jan 26 12:36:44 2001

Field Summary

protected String	m_lispRoot
protected static String	PROGRAMDATA_DIR

Constructor Summary

JavaToLisp()
Creates a new JavaToLisp instance.

JavaToLisp(boolean useFileToConnect)
Creates a new JavaToLisp instance.

Constructor Detail

JavaToLisp

public JavaToLisp()

Creates a new JavaToLisp instance.

JavaToLisp

public JavaToLisp(boolean useFileToConnect)

Creates a new JavaToLisp instance.

Parameters:

useFileToConnect - if true, uses a file to advertise ports. otherwise, connects directly on an open port

Method Detail

connectToLisp

public boolean connectToLisp()

Start a Lisp process (if one is not already running) and connect to JLinker. (Note: If you have trouble connecting to JLinker, check that old alisp processes have been killed (nicely) or wait several minutes til they die on their own. If you still have trouble, try using a file to connect by using the constructor that takes a boolean value.)

Returns:

true if connected, false if the Lisp process or JLinker could not be started.

shutdown

public void shutdown()

Disconnect from JLinker, and kill the Lisp process if it was started.
