class | Common_Info |
This struct contains the necessary information for every <Event_Handler> entry. The reason the event is not in this structure is because we need to pass an event array into WaitForMultipleObjects and therefore keeping the events seperate makes sense. More... | |
class | Current_Info |
This structure inherits from the common structure to add information for current entries. More... | |
class | Suspended_Info |
This structure inherits from the common structure to add information for suspended entries. More... | |
class | To_Be_Added_Info |
This structure inherits from the common structure to add information for <to_be_added> entries. More... | |

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 | to_be_removed_masks, | |||
int | operation | |||

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.

Check to see if handle is associated with a valid Event_Handler. Return Event_Handler and associated masks.
int ACE_WFMO_Reactor_Handler_Repository::handler | ( | ACE_HANDLE | handle, | |
ACE_Reactor_Mask | mask, | |||
ACE_Event_Handler ** | event_handler = 0 | |||
