Detailed Description

Used to map ACE_HANDLEs onto the appropriate Event_Tuple.

This class is simply a container that maps a handle to its corresponding event tuple. It is not meant for use outside of the Dev_Poll_Reactor.

Calls to any method in this class, and any modification to a Event_Tuple returned from this class's methods, must be made while holding the repository lock.

Member Function Documentation

int ACE_Dev_Poll_Reactor::Handler_Repository::bind ( ACE_HANDLE  handle,
ACE_Event_Handler handler,
ACE_Reactor_Mask  mask 

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

int ACE_Dev_Poll_Reactor::Handler_Repository::close ( void  )

Close down the repository.

void ACE_Dev_Poll_Reactor::Handler_Repository::dump ( void  ) const

Dump the state of an object.

ACE_Dev_Poll_Reactor::Event_Tuple * ACE_Dev_Poll_Reactor::Handler_Repository::find ( ACE_HANDLE  handle)

Return a pointer to the Event_Tuple associated with handle. If there is none associated, returns 0 and sets errno.

bool ACE_Dev_Poll_Reactor::Handler_Repository::handle_in_range ( ACE_HANDLE  handle) const
bool ACE_Dev_Poll_Reactor::Handler_Repository::invalid_handle ( ACE_HANDLE  handle) const
size_t ACE_Dev_Poll_Reactor::Handler_Repository::max_size ( void  ) const

Returns the current table size.

int ACE_Dev_Poll_Reactor::Handler_Repository::open ( size_t  size)

Initialize a repository that can map handles up to the value size. Since the event tuples are accessed directly using the handle as an index, size sets the maximum handle value, minus 1.

size_t ACE_Dev_Poll_Reactor::Handler_Repository::size ( void  ) const

Returns the current table size.

int ACE_Dev_Poll_Reactor::Handler_Repository::unbind ( ACE_HANDLE  handle,
bool  decr_refcnt = true 

Remove the binding for handle; optionally decrement the associated handler's reference count.

int ACE_Dev_Poll_Reactor::Handler_Repository::unbind_all ( void  )

Remove all the registered tuples.

Member Data Documentation


Declare the dynamic allocation hooks.

Event_Tuple* ACE_Dev_Poll_Reactor::Handler_Repository::handlers_

The underlying array of event handlers.

The array of event handlers is directly indexed directly using an ACE_HANDLE value. This is Unix-specific.

int ACE_Dev_Poll_Reactor::Handler_Repository::max_size_

Maximum number of handles.

int ACE_Dev_Poll_Reactor::Handler_Repository::size_

Current number of handles.
