Member Function Documentation

int ACE_WFMO_Reactor_Handler_Repository::bind	(	ACE_HANDLE	,
		ACE_Event_Handler *
	)

Bind the ACE_Event_Handler * to the ACE_HANDLE. This is for the simple event entry.

int ACE_WFMO_Reactor_Handler_Repository::bind_i	(	bool	io_entry,
		ACE_Event_Handler *	event_handler,
		long	network_events,
		ACE_HANDLE	io_handle,
		ACE_HANDLE	event_handle,
		bool	delete_event
	)

Insert I/O Event_Handler entry into the system. This method assumes that the lock are head before this method is invoked.

ACE_Reactor_Mask ACE_WFMO_Reactor_Handler_Repository::bit_ops	(	long &	existing_masks,
		ACE_Reactor_Mask	to_be_removed_masks,
		int	operation
	)

This method is used to change the network mask left (if any) after a remove request to <WFMO_Reactor>

bool ACE_WFMO_Reactor_Handler_Repository::changes_required ( void )

inlinevirtual

Check if changes to the handle set are required.

int ACE_WFMO_Reactor_Handler_Repository::close ( void )

inline

Close down the handler repository.

ACE_WFMO_Reactor_Handler_Repository::Current_Info * ACE_WFMO_Reactor_Handler_Repository::current_info ( void ) const

inline

Pointer to the beginning of the current array of ACE_Event_Handler *'s.

void ACE_WFMO_Reactor_Handler_Repository::dump ( void ) const

Dump the state of an object.

ACE_Event_Handler * ACE_WFMO_Reactor_Handler_Repository::find_handler ( ACE_HANDLE handle )

Return the Event_Handler associated with handle. Return 0 if handle is not registered.

int ACE_WFMO_Reactor_Handler_Repository::handler	(	ACE_HANDLE	handle,
		ACE_Reactor_Mask	mask,
		ACE_Event_Handler **	event_handler = `0`
	)

Check to see if handle is associated with a valid Event_Handler bound to mask. Return the event_handler associated with this handler if event_handler != 0.

ACE_Event_Handler * ACE_WFMO_Reactor_Handler_Repository::handler	(	ACE_HANDLE	handle,
		long &	existing_masks
	)

Check to see if handle is associated with a valid Event_Handler. Return Event_Handler and associated masks.

ACE_HANDLE * ACE_WFMO_Reactor_Handler_Repository::handles ( void ) const

inline

Pointer to the beginning of the current array of ACE_HANDLE *'s.

int ACE_WFMO_Reactor_Handler_Repository::invalid_handle ( ACE_HANDLE handle ) const

inline

int ACE_WFMO_Reactor_Handler_Repository::make_changes ( void )

inlinevirtual

Make changes to the handle set.

int ACE_WFMO_Reactor_Handler_Repository::make_changes_in_current_infos ( void )

Deletions and suspensions in current_info_.

int ACE_WFMO_Reactor_Handler_Repository::make_changes_in_suspension_infos ( void )

Deletions and resumptions in current_suspended_info_.

int ACE_WFMO_Reactor_Handler_Repository::make_changes_in_to_be_added_infos ( void )

Deletions in to_be_added_info_, or transfers to current_info_ or current_suspended_info_ from to_be_added_info_

DWORD ACE_WFMO_Reactor_Handler_Repository::max_handlep1 ( void ) const

inline

Maximum ACE_HANDLE value, plus 1.

int ACE_WFMO_Reactor_Handler_Repository::modify_network_events_i	(	ACE_HANDLE	io_handle,
		ACE_Reactor_Mask	new_masks,
		ACE_Reactor_Mask &	old_masks,
		long &	new_network_events,
		ACE_HANDLE &	event_handle,
		bool &	delete_event,
		int	operation
	)

This method is used to calculate the network mask after a mask_op request to <WFMO_Reactor>. Note that because the Event_Handler may already be in the handler repository, we may have to find the old event and the old network events

int ACE_WFMO_Reactor_Handler_Repository::open ( size_t size )

Initialize the repository of the appropriate size.

int ACE_WFMO_Reactor_Handler_Repository::remove_handler_i	(	size_t	slot,
		ACE_Reactor_Mask	mask
	)

Removes the ACE_Event_Handler at slot from the table.

int ACE_WFMO_Reactor_Handler_Repository::remove_suspended_handler_i	(	size_t	slot,
		ACE_Reactor_Mask	mask
	)

Removes the ACE_Event_Handler at slot from the table.

int ACE_WFMO_Reactor_Handler_Repository::remove_to_be_added_handler_i	(	size_t	slot,
		ACE_Reactor_Mask	to_be_removed_masks
	)

Removes the ACE_Event_Handler at slot from the table.

int ACE_WFMO_Reactor_Handler_Repository::resume_handler_i	(	ACE_HANDLE	handle,
		bool &	changes_required
	)

Resume suspended entry.

int ACE_WFMO_Reactor_Handler_Repository::scheduled_for_deletion ( size_t slot ) const

inline

Check to see if slot has been scheduled for deletion.

int ACE_WFMO_Reactor_Handler_Repository::suspend_handler_i	(	ACE_HANDLE	handle,
		bool &	changes_required
	)

Temporarily suspend entry.

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

inline

Remove the binding of ACE_HANDLE in accordance with the mask.

void ACE_WFMO_Reactor_Handler_Repository::unbind_all ( void )

Remove all bindings of <ACE_HANDLE, ACE_Event_Handler> tuples.

int ACE_WFMO_Reactor_Handler_Repository::unbind_i	(	ACE_HANDLE	handle,
		ACE_Reactor_Mask	mask,
		bool &	changes_required
	)

Non-lock-grabbing version of unbind.
