NAME

       find - search for classes and objects

SYNOPSIS

       itcl::find option ?arg arg ...?
_________________________________________________________________

DESCRIPTION

       The find command is used to find classes and objects that are available in the current interpreter.  Classes and objects are reported first
       in the active namespace, then in all other namespaces in the interpreter.

       The option argument determines what action is carried out by the command.  The legal options (which may be abbreviated) are:

       find classes ?pattern?
	      Returns a list of [incr Tcl] classes.  Classes in the current namespace are listed first, followed by classes in	all  other  names-
	      paces in the interpreter.  If the optional pattern is specified, then the reported names are compared using the rules of the "string
	      match" command, and only matching names are reported.

	      If a class resides in the current namespace context, this command reports its simple name--without any qualifiers.  However, if  the
	      pattern  contains  :: qualifiers, or if the class resides in another context, this command reports its fully-qualified name.  There-
	      fore, you can use the following command to obtain a list where all names are fully-qualified:
	      itcl::find classes ::*

       find objects ?pattern? ?-class className? ?-isa className?
	      Returns a list of [incr Tcl] objects.  Objects in the current namespace are listed first, followed by objects in	all  other  names-
	      paces in the interpreter.  If the optional pattern is specified, then the reported names are compared using the rules of the "string
	      match" command, and only matching names are reported.  If the optional "-class" parameter is specified, this list is  restricted	to
	      objects  whose  most-specific class is className.  If the optional "-isa" parameter is specified, this list is further restricted to
	      objects having the given className anywhere in their heritage.

	      If an object resides in the current namespace context, this command reports its simple name--without any	qualifiers.   However,	if
	      the  pattern  contains  ::  qualifiers,  or if the object resides in another context, this command reports its fully-qualified name.
	      Therefore, you can use the following command to obtain a list where all names are fully-qualified:
	      itcl::find objects ::*

NAME

       is - test argument to see if it is a class or an object

SYNOPSIS

       itcl::is option ?arg arg ...?
_________________________________________________________________

DESCRIPTION

       The is command is used to check if the argument given is a class or an object; depending on the option given. If the argument if a class or
       object, then 1 is returned. Otherwise, 0 is returned.  The is command also recognizes the commands wrapped in the itcl code command.

       The option argument determines what action is carried out by the command.  The legal options (which may be abbreviated) are:

       is class command
	      Returns 1 if command is a class, and returns 0 otherwise.

	      The fully qualified name of the class needs to be given as the command argument. So, if a class resides in  a  namespace,  then  the
	      namespace needs to be specified as well. So, if a class C resides in a namespace N, then the command should be called like:
	      is N::C
		  or
	      is ::N::C

       is object ?-class className? command
	      Returns 1 if command is an object, and returns 0 otherwise.

	      If  the  optional "-class" parameter is specified, then the command will be checked within the context of the class given. Note that
	      className has to exist. If not, then an error will be given. So, if className is uncertain to be a class, then the  programmer  will
	      need to check it's existance beforehand, or wrap it in a catch statement.

	      So, if c is an object in the class C, in namespace N then these are the possibilities (all return 1):
	      set obj [N::C c]
	      itcl::is object N::c
	      itcl::is object c
	      itcl::is object $obj
	      itcl::is object [itcl::code c]
