| bool CMSWindowsEventQueueBuffer::addEvent | ( | UInt32 | dataID | ) | [virtual] |
Post an event.
Add the given event to the end of the queue buffer. This is a user event and getEvent() must be able to identify it as such and return dataID. This method must cause waitForEvent() to return at some future time if it's blocked waiting on an event.
Implements IEventQueueBuffer.
Definition at line 116 of file CMSWindowsEventQueueBuffer.cpp.
| void CMSWindowsEventQueueBuffer::deleteTimer | ( | CEventQueueTimer * | ) | const [virtual] |
Destroy a timer object.
Destroy a timer object previously returned by newTimer().
Implements IEventQueueBuffer.
Definition at line 135 of file CMSWindowsEventQueueBuffer.cpp.
| IEventQueueBuffer::Type CMSWindowsEventQueueBuffer::getEvent | ( | CEvent & | event, | |
| UInt32 & | dataID | |||
| ) | [virtual] |
Get the next event.
Get the next event from the buffer. Return kNone if no event is available. If a system event is next, return kSystem and fill in event. The event data in a system event can point to a static buffer (because CEvent::deleteData() will not attempt to delete data in a kSystem event). Otherwise, return kUser and fill in dataID with the value passed to addEvent().

| bool CMSWindowsEventQueueBuffer::isEmpty | ( | ) | const [virtual] |
Check if event queue buffer is empty.
Return true iff the event queue buffer is empty.
Implements IEventQueueBuffer.

| CEventQueueTimer * CMSWindowsEventQueueBuffer::newTimer | ( | double | duration, | |
| bool | oneShot | |||
| ) | const [virtual] |
Create a timer object.
Create and return a timer object. The object is opaque and is used only by the buffer but it must be a valid object (i.e. not NULL).
Implements IEventQueueBuffer.
Definition at line 129 of file CMSWindowsEventQueueBuffer.cpp.
| void CMSWindowsEventQueueBuffer::waitForEvent | ( | double | timeout | ) | [virtual] |
Block waiting for an event.
Wait for an event in the event queue buffer for up to timeout seconds.
Implements IEventQueueBuffer.
