Class ZContext

  • All Implemented Interfaces:
    Closeable, AutoCloseable

    public class ZContext
    extends Object
    implements Closeable
    ZContext provides a high-level ZeroMQ context management class The ZContext class wraps java org.zeromq.Context objects, which in turn wrap native 0MQ contexts. It manages open sockets in the context and automatically closes these before terminating the context. It provides a simple way to set the linger timeout on sockets, and configure contexts for number of I/O threads. Sets-up signal (interrupt) handling for the process.

      • destroy

        public void destroy()
        Destructor. Call this to gracefully terminate context and close any managed 0MQ sockets
      • createSocket

        public ZMQ.Socket createSocket​(int type)
        Creates a new managed socket within this ZContext instance. Use this to get automatic management of the socket at shutdown
        Parameters:
        type - socket type (see ZMQ static class members)
        Returns:
        Newly created Socket object
      • destroySocket

        public void destroySocket​(ZMQ.Socket s)
        Destroys managed socket within this context and remove from sockets list
        Parameters:
        s - org.zeromq.Socket object to destroy
      • shadow

        public static ZContext shadow​(ZContext ctx)
        Creates new shadow context. Shares same underlying org.zeromq.Context instance but has own list of managed sockets, io thread count etc.
        Parameters:
        ctx - Original ZContext to create shadow of
        Returns:
        New ZContext
