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.

Member Typedef Documentation

typedef ACE_HANDLE ACE_Select_Reactor_Handler_Repository::key_type

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.

Constructor & Destructor Documentation

ACE_Select_Reactor_Handler_Repository::ACE_Select_Reactor_Handler_Repository

(

ACE_Select_Reactor_Impl &

select_reactor

)

Default "do-nothing" constructor.

Member Function Documentation

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.

ACE_Event_Handler * ACE_Select_Reactor_Handler_Repository::find ( ACE_HANDLE  handle )

inline

Return the ACE_Event_Handler* associated with ACE_HANDLE.

ACE_Select_Reactor_Handler_Repository::map_type::iterator ACE_Select_Reactor_Handler_Repository::find_eh ( ACE_HANDLE  handle )

private

Returns

iterator corresponding ACE_Event_Handler* associated with ACE_HANDLE.

bool ACE_Select_Reactor_Handler_Repository::handle_in_range

(

ACE_HANDLE

handle

)

bool ACE_Select_Reactor_Handler_Repository::invalid_handle

(

ACE_HANDLE

handle

)

ACE_Select_Reactor_Handler_Repository::max_handlep1_type ACE_Select_Reactor_Handler_Repository::max_handlep1 ( void  ) const

inline

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.

ACE_Select_Reactor_Handler_Repository::size_type ACE_Select_Reactor_Handler_Repository::size ( void  ) const

inline

Returns the current table size.

int ACE_Select_Reactor_Handler_Repository::unbind ( ACE_HANDLE  handle, ACE_Reactor_Mask  mask  )

inline

Remove the binding of ACE_HANDLE in accordance with the mask.

int ACE_Select_Reactor_Handler_Repository::unbind ( ACE_HANDLE  handle, map_type::iterator  pos, ACE_Reactor_Mask  mask  )

private

Remove the binding of handle corresponding to position pos in accordance with the mask.

int ACE_Select_Reactor_Handler_Repository::unbind_all

(

void

)

Remove all the <ACE_HANDLE, ACE_Event_Handler> tuples.
