 public Commands()

 public static void newCmd(String argv[]) throws TclException

Implements nsjava::new command in Tcl. Object handle is set in the interpreter.

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void nullCmd(String argv[]) throws TclException

Implements nsjava::null command in Tcl. Null Object handle is set in the interpreter.

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void isnullCmd(String argv[]) throws TclException

Implements nsjava::isnull command in Tcl. Tests the java object handle to see if the object is null. Set's the Tcl interpreter result to a boolean result.

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void callCmd(String argv[]) throws TclException

Implements nsjava::call command in Tcl. Used to call static methods from Tcl

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void fieldCmd(String argv[]) throws TclException

Implements nsjava::field command in Tcl. Used to call access class or instance fields.

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void castCmd(String argv[]) throws TclException

Implements nsjava::cast command in Tcl. Used to cast a java object handle to a new object type. New type must be assignable or an exception is thrown.

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void instanceofCmd(String argv[]) throws TclException

Implements nsjava::isinstanceof command in Tcl. Used to test a java object handle to see if it is an instance of a specified class.

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void throwCmd(String argv[]) throws TclException

Implements nsjava::throw command in Tcl. Used to throw a passed in object handle as an exception. The object to be thrown, must be an instance of throwable.

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void tryCmd(String argv[]) throws TclException

Implements nsjava::try command in Tcl. Used to catch java exceptions from within Tcl. Used as a replacement for Tcl's catch command when trapping errors from nsjava commands.

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void infoCmd(String argv[]) throws TclException

Implements nsjava::info command in Tcl. Used to introspect java objects from within Tcl.

Parameters:

argv - argument list passed to command

Throws: TclException

thrown for usage errors

 public static void instanceCmd(String argv[]) throws TclException

Implements instance commands in Tcl. Used to call instance methods from within Tcl. As an example to create a new instance and call an instance method, you might do the following: set x [nsjava::new {SomeClass java.lang.String} {Hello World}] $x some_method // some_method is called via this command

Parameters:

argv - argument list passed to command
