public interface Command

The Command interface specifies the method that a new Tcl command must implement. See the createCommand method of the Interp class to see how to add a new command to an interperter.

Method Summary

void	cmdProc(Interp interp, TclObject[] objv) This method implements the functionality of the command.

Method Detail

cmdProc

void cmdProc(Interp interp,
             TclObject[] objv)
             throws TclException

This method implements the functionality of the command. However, calling it directly in application code will bypass execution traces. Instead, commands should be called with WrappedCommand.invoke

Parameters:

interp - The interpreter for setting the results and which contains the context

objv - the argument list for the command; objv[0[ is the command name itself

Throws:

TclException - on any errors
