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.

ACE_INLINE ACE_Select_Reactor_Handler_Repository::~ACE_Select_Reactor_Handler_Repository (  void    )

Destructor.

Member Function Documentation

int ACE_Select_Reactor_Handler_Repository::bind (  ACE_HANDLE   , ACE_Event_Handler *   , ACE_Reactor_Mask    )

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

ACE_Select_Reactor_Handler_Repository::ACE_ALLOC_HOOK_DECLARE

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.

ACE_Select_Reactor_Impl& ACE_Select_Reactor_Handler_Repository::select_reactor_ [private]

Reference to our <Select_Reactor>.
