RawSynchronousSocket class

A low-level class for communicating synchronously over a TCP socket.

Warning: RawSynchronousSocket should probably only be used to connect to 'localhost'. The operations below will block the calling thread to wait for a response from the network. The thread can process no other events while waiting for these operations to complete. RawSynchronousSocket is not suitable for applications that require high performance or asynchronous I/O such as a server. Instead such applications should use the non-blocking sockets and asynchronous operations in the Socket or RawSocket classes.

Constructors

RawSynchronousSocket()

Properties

address → InternetAddress

Methods

available() → int
Returns the number of received and unread bytes in the socket that can be read.
closeSync() → void
Closes the RawSynchronousSocket. [...]
readIntoSync(List<int> buffer, [ int start = 0, int end ]) → int
Reads into an existing List<int> from the socket into the range: [start,end). [...]
readSync(int bytes) → List<int>
Reads up to bytes bytes from the socket. [...]
shutdown(SocketDirection direction) → void
Shutdown a socket in the provided direction. [...]
writeFromSync(List<int> buffer, [ int start = 0, int end ]) → void
Writes data from a specified range in a List<int> to the socket. [...]
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
toString() → String
Returns a string representation of this object.

Operators

operator ==(dynamic other) → bool
The equality operator. [...]

Static Methods

connectSync(dynamic host, int port) → RawSynchronousSocket
Creates a new socket connection and returns a RawSynchronousSocket. [...]
