NAME
       nx::next	- Skip to the next most	specific method	implementation

SYNOPSIS
       next ?arguments?

______________________________________________________________________________

DESCRIPTION
       next ?arguments?
	      This  command  is	 invoked inside	a method body to call the next
	      most specific method implementation in  the  list	 of  available
	      methods.	This list of available methods is specific to the cur-
	      rent method-call context.	This context is	set by the usage  con-
	      text  of	nx::next (method combination vs. method-call intercep-
	      tion; see	below).	The optional arguments are the argument	values
	      to  be passed into the next most specific	method implementation.
	      If omitted, the arguments	of the current method call  are	 auto-
	      matically	 forwarded.  To	call the next most specific method im-
	      plementation without arguments (or to suppress argument forward-
	      ing), arguments must be set to an	empty string. To pass an empty
	      string as	a (single) argument value, protect it as a  list.  The
	      result of	a call to nx::next is the result of the	next most spe-
	      cific method implementation.  If there are no more  further  ap-
	      plicable	methods, the result of nx::next	will depend on its us-
	      age context: method combination or method-call interception.  If
	      nx::next	is  used  in a method body for method combination, the
	      result will be an	empty string. If nx::next is used in the  body
	      of a filter method for method-call interception, the result will
	      be an error.

	      When executing a method call, the	NX dispatch mechanism computes
	      a	 list of applicable method implementations for the method name
	      requested	from a given object receiving the call;	in support  of
	      method combination and method-call interception.

	      For  method  combination,	the computed list contains any object-
	      local method implementation and any method  implementations  in-
	      herited  by  the object from the classes in its precedence list.
	      Examples are overloading method implementations in the class hi-
	      erarchy  of the object, as well as from mixin classes of the ob-
	      ject. For	method-call interception, the computed	list  contains
	      the applicable filter methods, again ordered by their definition
	      order according to the precedence	list of	the called object.

	      To retrieve the next most	specific method	implementation	to  be
	      invoked  by  nx::current	from  the internally computed list, if
	      any, use nx::current.
