class ACE_Select_Reactor_Handler_Repository_Iterator

Detailed Description

Used to map ACE_HANDLEs onto the appropriate ACE_Event_Handler *.

This class is necessary to shield differences between UNIX and Win32. In UNIX, ACE_HANDLE is an int, whereas in Win32 it's a void *. This class hides all these details from the bulk of the ACE_Select_Reactor code. All of these methods are called with the main <Select_Reactor> token lock held.

Member Typedef Documentation

The NT version implements this via a hash map ACE_Event_Handler*. Since NT implements ACE_HANDLE as a void * we can't directly index into this array. Therefore, we must explicitly map ACE_HANDLE to ACE_Event_Handler.

Constructor & Destructor Documentation

ACE_Select_Reactor_Handler_Repository::ACE_Select_Reactor_Handler_Repository ( ACE_Select_Reactor_Impl select_reactor  ) 

Default "do-nothing" constructor.

Member Function Documentation

int ACE_Select_Reactor_Handler_Repository::open ( size_type  size  ) 

Initialize a repository of the appropriate size.

On Unix platforms, the size parameter should be as large as the maximum number of file descriptors allowed for a given process. This is necessary since a file descriptor is used to directly index the array of event handlers maintained by the Reactor's handler repository. Direct indexing is used for efficiency reasons.

int ACE_Select_Reactor_Handler_Repository::close ( void   ) 

Close down the repository.

ACE_INLINE ACE_Event_Handler * ACE_Select_Reactor_Handler_Repository::find ( ACE_HANDLE  handle  ) 

Return the ACE_Event_Handler* associated with ACE_HANDLE.

int ACE_Select_Reactor_Handler_Repository::bind ( ACE_HANDLE  handle,
ACE_Event_Handler event_handler,
ACE_Reactor_Mask  mask 

Bind the ACE_Event_Handler * to the ACE_HANDLE with the appropriate ACE_Reactor_Mask settings.

ACE_INLINE int ACE_Select_Reactor_Handler_Repository::unbind ( ACE_HANDLE  handle,
ACE_Reactor_Mask  mask 

Remove the binding of ACE_HANDLE in accordance with the mask.

int ACE_Select_Reactor_Handler_Repository::unbind_all ( void   ) 

Remove all the <ACE_HANDLE, ACE_Event_Handler> tuples.

bool ACE_Select_Reactor_Handler_Repository::invalid_handle ( ACE_HANDLE  handle  ) 

bool ACE_Select_Reactor_Handler_Repository::handle_in_range ( ACE_HANDLE  handle  ) 

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE ACE_Select_Reactor_Handler_Repository::size_type ACE_Select_Reactor_Handler_Repository::size ( void   )  const

Returns the current table size.

ACE_INLINE ACE_Select_Reactor_Handler_Repository::max_handlep1_type ACE_Select_Reactor_Handler_Repository::max_handlep1 ( void   )  const

Maximum ACE_HANDLE value, plus 1.

void ACE_Select_Reactor_Handler_Repository::dump ( void   )  const

Dump the state of an object.

int ACE_Select_Reactor_Handler_Repository::unbind ( ACE_HANDLE  handle,
map_type::iterator  pos,
ACE_Reactor_Mask  mask 
) [private]

Remove the binding of handle corresponding to position pos in accordance with the mask.

ACE_Select_Reactor_Handler_Repository::map_type::iterator ACE_Select_Reactor_Handler_Repository::find_eh ( ACE_HANDLE  handle  )  [private]

iterator corresponding ACE_Event_Handler* associated with ACE_HANDLE.
