collection of the small table in memory still does not hold, this time can use Bloomfiler to save space.
The most common function of bloomfilter is to determine whether an element is in a set. Its two most important methods are: Add () and contains (). The biggest feature is that false negative is not present, that is, if contains () returns false, the element must not be in the collection, but there is a certain true negative, that is, if contains () returns True, the element may be in the col

isolation of FTTP networks poses two major challenges to technicians. First, once the OTDR tracking signal encounters a splitter in the fdt, it is difficult to transmit the signal from CO. Therefore, the technician must access the network at the FDT. If all FDT connection points have been fused, the weld line needs to be opened by the welder. After tracking, the splitter must be refused to the allocated op

Csplitterwnd class
The csplitterwnd class provides a splitter window, which contains multiple panes. The pane is usually an application-specificCviewDerived object, but it can also be any cwnd object with an appropriate subwindow ID.
A csplitterwnd object is usually embedded into a cframewnd or javasichildwnd parent object. Follow these steps to create a csplitterwnd object:

Both reactor and preactor are Io multiplexing modes. Generally, the I/O multiplexing mechanism depends on an event multiplexing (EventDemultiplexer ). The splitter object can separate the I/O events from the event source and distribute them to the corresponding read/write event processor (EventHandler ). The developer registers the event to be processed and its event processor (or callback function) in advance ).
The reactor mode adopts synchronous Io
