ist.palcom.assemblies
Class Assembly

java.lang.Object
  extended by ist.palcom.services.AbstractService
      extended by ist.palcom.assemblies.Assembly
All Implemented Interfaces:
Service, IHgraphNode
Direct Known Subclasses:
ScriptedAssembly
public class Assembly
extends AbstractService

An Assembly is a service that manages a set of connections, and that can have a script coordinating services. The assembly info is read from disk and stored on disk for later use. The infos are stored after each update, for robustness.

Field Summary
 PRDAssemblyVer assemblyVer
          The AssemblyInfo for this assembly.
protected  ist.palcom.assemblies.Assembly.CommandThread commandThread
           
protected  boolean[] connectionEstablished
           
protected  ist.palcom.assemblies.Assembly.DebugService debugService
