# dispatch
a project
use a simple timer(priority queue) to simulate the event
one thread is to read file , another thread is timer, when the event be touch , then notify.
architecture:
file information :
data.h: a template data struct , include hash map(use for matched strategy) and priority queue(use for FIFO strategy )
dispatch.h: implement of two strategy. notify event and statistics average food wait time and courier wait time
error.h: error code
type.h: base type
server.h: manager source and implement read file.
demo:
int ProductOrder(Server* server, const char* file)
{
pthread_setname_np(pthread_self(), "product");
return server->ReadData(file);
}
int TryDispatchOrder(Server* server)
{
pthread_setname_np(pthread_self(), "dispatch");
return server->TryDispatchOrder();
}
int main()
{
Config conf;
conf.st = STRATEGIE_MATCH; // STRATEGIE_MATCH
string file = "data2.json";
conf.cap = DEFAULT_MAX_QUEUE_SIZE;
Server server;
server.InitServer(&conf);
thread read(ProductOrder, &server, file.c_str());
thread disp(TryDispatchOrder, &server);
read.join();
disp.join();
server.DeInitServer();
}
compile information:
compiler: gcc
cmake: above VERSION 3.16
build Server:
cmake .
make clean && make
./Server
build Test: must build Server before build Test
cd test
cmake .
make clean && make
./Test
