| class | ACE_Stream_Iterator< ACE_SYNCH_USE > |
A Stream consists of a stack of <ACE_Modules>, each of which contains two <ACE_Tasks>. Even though the methods in this class are virtual, this class isn't really intended for subclassing unless you know what you are doing. In particular, the <ACE_Stream> destructor calls <close>, which won't be overridden properly unless you call it in a subclass destructor.
