Method Detail

init

public void init(Interp interp)
          throws TclException

Description copied from class: Extension

Initialize the Extension to run in a normal (unsafe) interpreter. This usually means creating all the commands provided by this class. A particular implementation can arrange the commands to be loaded on-demand using the loadOnDemand() function.

Specified by:

init in class Extension

Parameters:

interp - current interpreter.

Throws:

TclException

safeInit

public void safeInit(Interp safeInterp)
              throws TclException

Description copied from class: Extension

Initialize the Extension to run in a safe interpreter. This method should be written carefully, so that it initializes the safe interpreter only with partial functionality provided by the Extension that is safe for use by untrusted code. The default implementation always throws a TclException, so that a subclass of Extension cannot be loaded into a safe interpreter unless it has overridden the safeInit() method.

Overrides:

safeInit in class Extension

Parameters:

safeInterp - the safe interpreter in which the Extension should be initialized.

Throws:

TclException

cmdProc

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

Description copied from interface: Command

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

Specified by:

cmdProc in interface Command

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
