|
*based on the SocketIO library created by LearnBoost at http://socket.io
|
|
*using spec version 1 found at https://github.com/LearnBoost/socket.io-spec
|
|
|
|
Usage is described below, a full working example can be found in TestCpp under ExtionsTest/NetworkTest/SocketIOTest
|
|
|
|
creating a new connection to a socket.io server running at localhost:3000
|
|
|
|
SIOClient *client = SocketIO::connect(*delegate, "ws://localhost:3000");
|
|
|
|
the connection process will begin and if successful delegate::onOpen will be called
|
|
if the connection process results in an error, delegate::onError will be called with the err msg
|
|
|
|
sending a message to the server
|
|
|
|
client->send("Hello!");
|
|
|
|
emitting an event to be handled by the server, argument json formatting is up to you
|
|
|
|
client->emit("eventname", "[{\"arg\":\"value\"}]");
|
|
|
|
registering an event callback, target should be a member function in a subclass of SIODelegate
|
|
CC_CALLBACK_2 is used to wrap the callback with std::bind and store as an SIOEvent
|
|
|
|
client->on("eventname", CC_CALLBACK_2(TargetClass::targetfunc, *targetclass_instance));
|
|
|
|
event target function should match this pattern, *this pointer will be made available
|
|
|
|
void TargetClass::targetfunc(SIOClient *, const std::string&)
|
|
|
|
disconnect from the endpoint by calling disconnect(), onClose will be called on the delegate once complete
|
|
in the onClose method the pointer should be set to NULL or used to connect to a new endpoint
|
|
|
|
client->disconnect();
|
|
