class ACE_Select_Reactor_Handler_Repository_Iterator

Detailed Description

Used to map <ACE_HANDLE>s 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.

Constructor & Destructor Documentation

ACE_Select_Reactor_Handler_Repository::ACE_Select_Reactor_Handler_Repository ACE_Select_Reactor_Impl  ) 

Default "do-nothing" constructor.

Member Function Documentation

int ACE_Select_Reactor_Handler_Repository::bind ACE_HANDLE  ,
ACE_Event_Handler ,

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

int ACE_Select_Reactor_Handler_Repository::close void   ) 

Close down the repository.

void ACE_Select_Reactor_Handler_Repository::dump void   )  const

Dump the state of an object.

ACE_Event_Handler * ACE_Select_Reactor_Handler_Repository::find ACE_HANDLE  handle,
size_t *  index_p = 0

Return the <ACE_Event_Handler *> associated with <ACE_HANDLE>. If <index_p> is non-0, then return the index location of the <handle>, if found.

int ACE_Select_Reactor_Handler_Repository::handle_in_range ACE_HANDLE  handle  ) 

int ACE_Select_Reactor_Handler_Repository::invalid_handle ACE_HANDLE  handle  ) 

size_t ACE_Select_Reactor_Handler_Repository::max_handlep1 void   ) 

Maximum ACE_HANDLE value, plus 1.

int ACE_Select_Reactor_Handler_Repository::open size_t  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.

ACE_INLINE size_t ACE_Select_Reactor_Handler_Repository::size void   )  const

Returns the current table size.

int ACE_Select_Reactor_Handler_Repository::unbind ACE_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.

Member Data Documentation


Declare the dynamic allocation hooks.

ACE_Event_Tuple* ACE_Select_Reactor_Handler_Repository::event_handlers_ [private]

The NT version implements this via a dynamically allocated array of <ACE_Event_Tuple *>. Since NT implements ACE_HANDLE as a void * we can't directly index into this array. Therefore, we just do a linear search (for now). Next, we'll modify things to use hashing or something faster...

int ACE_Select_Reactor_Handler_Repository::max_handlep1_ [private]

The highest currently active handle, plus 1 (ranges between 0 and <max_size_>.

ssize_t ACE_Select_Reactor_Handler_Repository::max_size_ [private]

Maximum number of handles.
