public abstract class JacobRunnable
extends JacobObject

Base class for process abstractions. An abstraction is a parameterized process template, whose instantiation is termed a concretion. Abstractions may define a set of bound channel names or other parameters which are resolved at the time of the concretion. For example the process term abstraction of a memory cell: Cell(s,v) := s ? { read(...) = ... & write(...) = ... } would be represented by the following Java class:

 public class Cell extends JacobRunnable {
     private CellChannel s;

     private Object v;

     public Cell(CellChannel s, Object v) {
         this.s = s;
         this.v = v;
     }

     public void run() {
      object(new CellChannelListener(s) { read(...) {...}
                             write(...) {...} } );
    }
 }
 

An example of the Java expression representing the concretion of this abstraction would look like:

    .
    .
    // (new c) Cell(c,v)
    Integer v = Integer.valueOf(0);
    CellChannel c = (CellChannel)newChannel(CellChannel.class);
    instance(new Cell(c, v));
    .
    .

getImplementedMethods

public java.util.Set<java.lang.reflect.Method> getImplementedMethods()

Specified by:

getImplementedMethods in class JacobObject

run

public abstract void run()

Peform the template reduction, i.e. do whatever it is that the templetized process does. This method may do some combination of in-line Java, and JACOB operations.

Note that JACOB operations are performed in parallel, so the sequencing of JACOB operations is irrelevant

toString

public java.lang.String toString()
