## 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.

## 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>.
