channel

What does it mean for a ChannelFactory to have a State property? I understand that a created channel can have connection based states. But am confused as to why the ChannelFactory also has such connection states. Does it too connect to the WCF service? A ChannelFactory object has a State because it is a CommunicationObject , and all CommunicationObjects in WCF have a State . Of course, that's just begging the question, and not really helpful. The real question boils down to two parts Why does ChannelFactory derive from CommunicationObject What does its State actually means? The second one is

I am trying to use asynchronousFileChannel to write the date into a text file. I made 3 jar file of the program with the AsynchronousFileChannel and compiled all 3 jars simultaneously through command prompt to read 3 different text files and output to one common temporary file I have 2000 records in my test files(3) to be read,but the output in the common temporary file is missing some of the records,the output should have 6000 records but it shows only 5366 or 5666 or sometimes less than that. I am not able to figure out why some data is lost as it is the functionality of a

Is it possible to send messages to multiple rooms using socket.io? Sending to 1 room: io.sockets.in(room).emit("id", {}) Sending to N rooms: io.sockets.in(room1, room2, roomN).emit("id", {}) The sockets.in method only accepts one room as an argument, so to broadcast to multiple rooms you would have to reset the room, in between emissions. Something like this should work: ['room1', 'room2', 'room3'].forEach(function(room){ io.sockets.in(room).emit("id", {}); }); Yes, it's possible to emit to multiple rooms altogether. From the tests : socket.on('emit', function(room){ sio.in('woot').in('test')

What is a pseudo-tcp channel and how can it be implemented? Brian White Pseudo-TCP is a protocol that implements some of the ideas of TCP to provide a reliable data stream over an unreliable, packet-based interface. This could be used, for example, if you had access to only UDP but wanted a reliable way to pass data. You can find example code here: Google Code - PseudoTCP Channel (Header File) Google Code - PseudoTCP Channel (CC File) 来源： https://stackoverflow.com/questions/5570663/pseudo-tcp-channel

The idea is to have a variable number of channels in a slice, push each value received through them into a single channel, and close this output channel once the last one of the input channels is closed. Something like this, but for a number of channels more than two: func multiplex(cin1, cin2, cout chan int) { n := 2 for { select { case v, ok := <-cin1: if ok { cout <- v } else { n -= 1 } case v, ok := <-cin2: if ok { cout <- v } else { n -= 1 } } if n == 0 { close(cout) break } } } The above code avoids busy looping since there is no default case, which is good (EDIT: it looks like the

I am having issues with conda. After running commands such as: conda install -c /my_conda_channel numpy --offline --override-channels the default conda channel has now become 'my_conda_channel' so that each subsequent package from this channel supercedes the default channel, which is not what I want. I did the former just for testing purposes. How do I reset the channel behaviour? Change the order from ~/.condarc so that defaults the first channel as channels: - defaults - conda-forge and add this line to it channel_priority: true or run the following code in command-line conda config --set
