Interface OtpTransportFactory

  • All Known Implementing Classes:
    AbstractNode, OtpGenericTransportFactory, OtpLocalNode, OtpNode, OtpPeer, OtpSelf, OtpServer, OtpSocketTransportFactory
    public interface OtpTransportFactory
    Factory class used to create client- and server-side transport instances. One static instance of class implementing this interface is created when program loaded. Default implementation used is OtpSocketTransportFactory. JInterface user can specify custom transport factory implementing this interface in the following ways:
    defining static class as internal to class holding main() method
    In the systems, where main class can be retrieved with System.getProperty("sun.java.command"), user can define static class OtpErlangSystemTuner internal to the main class, providing at least one static method with the name getOtpTransportFactory, with no parameters, returning object of class implementing OtpTransportFactory, for example: 
     
 public class MyMainClass {
 
     public static class OtpErlangSystemTuner {
         ...
         public static OtpTransportFactory getOtpTransportFactory() {
             return new MyTransportFactory();
         }
     }
 
     public static class MyTransportFactory implements OtpTransportFactory {
         ...
     }
 
     public static void main(String[] args) {
         ...
     }
 }
    specifying factory class in the system properties
    User-defined transport factory class may be specified via system property OtpTransportFactory, for example: 
     
 package com.my.company;
 
 public static class MyTransportFactory implements OtpTransportFactory {
     ...
 }
    In such case program may be run with -DOtpTransportFactory=com.my.company.MyTransportFactory, or other way of setting system property before execution of static initializers may be used.
