class | ACE_Select_Reactor_Handler_Repository_Iterator |
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.

typedef ACE_Hash_Map_Manager_Ex<key_type, value_type, ACE_Hash<key_type>, std::equal_to<key_type>, ACE_Null_Mutex> ACE_Select_Reactor_Handler_Repository::map_type |
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
.
ACE_Select_Reactor_Handler_Repository::ACE_Select_Reactor_Handler_Repository | ( | ACE_Select_Reactor_Impl & | select_reactor | ) |
Default "do-nothing" constructor.
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.
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.

Maximum ACE_HANDLE value, plus 1.
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.
