The Traversable interface

INTRODUCTION

	Interface to detect if a class is traversable using foreach.

	Abstract base interface that cannot be implemented alone. Instead it must be implemented by either IteratorAggregate or Iterator.

       Note

	       Internal (built-in) classes that implement this interface can be used in a foreach construct and do not need to implement Iterator-
	      Aggregate or Iterator.

       Note

	       This is an internal engine interface which cannot be implemented in PHP scripts. Either IteratorAggregate or Iterator must be  used
	      instead.	When  implementing an interface which extends Traversable, make sure to list IteratorAggregate or Iterator before its name
	      in the implements clause.

INTERFACE SYNOPSIS

       Traversable

       Traversable

	This interface has no methods, its only purpose is to be the base interface for all traversable classes.

CosPropertyService_PropertyNamesIterator(3erl)		     Erlang Module Definition		    CosPropertyService_PropertyNamesIterator(3erl)

NAME

       CosPropertyService_PropertyNamesIterator - This module implements the OMG CosPropertyService::PropertyNamesIterator interface.

DESCRIPTION

       To get access to the record definitions for the structures use:
       -include_lib("cosProperty/include/CosPropertyService.hrl").

EXPORTS

       reset(Iterator) -> ok

	      Types  Iterator = #objref

	      This operation resets the position to the first property name.

       next_one(Iterator) -> Reply

	      Types  Iterator = #objref
		     Reply = {boolean(), Name}
		     Name = string()

	      This  operation  returns	true  if a Property Name exists at the current position and the out parameter is a valid Property Name. If
	      false is returned the out parameter is a non-valid Property Name.

       next_n(Iterator, HowMany) -> Reply

	      Types  Iterator = #objref
		     HowMany = long()
		     Reply = {boolean(), [Name]}
		     Name = string()

	      This operation returns true if the requested number of Property Names can be delivered and there are additional property	names.	If
	      false is returned a sequence of max HowMany property names will be returned and no more Property Names can be delivered.

       destroy(Iterator) -> ok

	      Types  Iterator = #objref

	      This operation will terminate the Iterator and all subsequent calls will fail.
