StreamingSocket * | waitForNextConnection () const |
A wrapper for a streaming (TCP) socket.
This allows low-level use of sockets; for an easier-to-use messaging layer on top of sockets, you could also try the InterprocessConnection class.
StreamingSocket::StreamingSocket | ( | ) |
Creates an uninitialised socket.
To connect it, use the connect() method, after which you can read() or write() to it.
To wait for other sockets to connect to this one, the createListener() method enters "listener" mode, and can be used to spawn new sockets for each connection that comes along.
StreamingSocket::~StreamingSocket | ( | ) |
Destructor.
bool StreamingSocket::bindToPort | ( | int | localPortNumber | ) |
Binds the socket to the specified local port.
Binds the socket to the specified local port and local address.
If localAddress is not an empty string then the socket will be bound to localAddress as well. This is useful if you would like to bind your socket to a specific network adapter. Note that localAddress must be an IP address assigned to one of your network address otherwise this function will fail.
void StreamingSocket::close | ( | ) |
Closes the connection.
bool StreamingSocket::connect | ( | const String & | remoteHostname, |
int | remotePortNumber, | ||
int | timeOutMillisecs = 3000 |
||
) |
Tries to connect the socket to hostname:port.
If timeOutMillisecs is 0, then this method will block until the operating system rejects the connection (which could take a long time).
Puts this socket into "listener" mode.
When in this mode, your thread can call waitForNextConnection() repeatedly, which will spawn new sockets for each new connection, so that these can be handled in parallel by other threads.
portNumber | the port number to listen on |
localHostName | the interface address to listen on - pass an empty string to listen on all addresses |
|
noexcept |
Returns the local port number to which this socket is currently bound.
This is useful if you need to know to which port the OS has actually bound your socket when calling the constructor or bindToPort with zero as the localPortNumber argument. Returns -1 if the function fails.
Returns the name of the currently connected host.
|
inlinenoexcept |
Returns the port number that's currently open.
|
inlinenoexcept |
Returns the OS's socket handle that's currently open.
|
inlinenoexcept |
True if the socket is currently connected.
|
noexcept |
True if the socket is connected to this machine rather than over the network.
int StreamingSocket::read | ( | void * | destBuffer, |
int | maxBytesToRead, | ||
bool | blockUntilSpecifiedAmountHasArrived | ||
) |
Reads bytes from the socket.
If blockUntilSpecifiedAmountHasArrived is true, the method will block until maxBytesToRead bytes have been read, (or until an error occurs). If this flag is false, the method will return as much data as is currently available without blocking.
StreamingSocket * StreamingSocket::waitForNextConnection | ( | ) | const |
When in "listener" mode, this waits for a connection and spawns it as a new socket.
The object that gets returned will be owned by the caller.
This method can only be called after using createListener().
int StreamingSocket::waitUntilReady | ( | bool | readyForReading, |
int | timeoutMsecs | ||
) | const |
Waits until the socket is ready for reading or writing.
If readyForReading is true, it will wait until the socket is ready for reading; if false, it will wait until it's ready for writing.
If the timeout is < 0, it will wait forever, or else will give up after the specified time.
If the socket is ready on return, this returns 1. If it times-out before the socket becomes ready, it returns 0. If an error occurs, it returns -1.
int StreamingSocket::write | ( | const void * | sourceBuffer, |
int | numBytesToWrite | ||
) |
Writes bytes to the socket from a buffer.
Note that this method will block unless you have checked the socket is ready for writing before calling it (see the waitUntilReady() method).
