## Interface JacobThread

-     public interface JacobThread

  Class exposing the JACOB operations.

  Note: these operations represent a subset of a process algebra mapped into Java invocations; other aspects of the syntax are represented natively in Java. In particular, parallel composition is modelled as sequential Java invocation and if-else are modelled using Java's if-else statement. Note also that the scoping rules for channel names are simply the Java object visibility rules.

- - ### Method Detail

    - #### getExtension

          java.lang.Object getExtension(java.lang.Class extensionClass)

    - #### exportChannel

          java.lang.String exportChannel(Channel channel)

    - #### importChannel

          Channel importChannel(java.lang.String channelId,
                                java.lang.Class channelClass)

    - #### instance

          void instance(JacobRunnable concretion)

      Create a process instance i.e. a concretion of a process abstraction.

    - #### message

          Channel message(Channel channel,
                          java.lang.reflect.Method method,
                          java.lang.Object[] args)

      Send a message (object invocation). This method shouldn't really be used as `Channel` objects may be used as proxies in this respect.
      Parameters:
        `channel` - channel on which to send the message
        `method` - method to apply
        `args` - arguments

    - #### newChannel

          Channel newChannel(java.lang.Class channelType,
                             java.lang.String creator,
                             java.lang.String description)

      Create a new channel.

    - #### object

          void object(boolean replicate,
                      ChannelListener methodList)
               throws java.lang.IllegalArgumentException

      Receive a message on a channel, allowing for possible replication. The effect of this method is to register a listener (the method list) for a message on the channel to consume either one or an infinate number of messages on the channel (depending on the value of the `replicate` argument.

      With respect to process terms, the Java expression `object(false, x, ChannelListener)` corresponds to the process term `x ? { ChannelListener }`; if in the same expression the initial `replicate` parameter were instead set to `true`, corresponding term would be `! x ? { ChannelListener }`.

      Parameters:
        `replicate` - if set the a replication operator is present
        `methodList` - object representation of the method list
      Throws:
        `java.lang.IllegalArgumentException` - if the method list does not match the channel kind

    - #### object

          void object(boolean reaplicate,
                      ChannelListener[] methodLists)
               throws java.lang.IllegalArgumentException

      Throws:
        `java.lang.IllegalArgumentException`
