All Implemented Interfaces:

public class VMPathCtx
extends ConceptCtx
implements IRuntimeConceptCtx

The VMPathCtx is the runtime representation of a path defined in a Brahms model with extensions for use in the virtual machine. The path context is put in place for handling possible messaging in a distributed environment, currently a path cannot do anything with messages it receives, but a message receiver must be implemented in order for a path to be registered in an agent directory.

Constructor Detail

VMPathCtx

public VMPathCtx(Path p)

Constructor, creates a new context for the specified path.

Parameters:

p - the Path for which to create a context

Method Detail

initialize

public void initialize(gov.nasa.arc.brahms.vm.controller.VMController vmc,
                       long time)
                throws VMException

Initializes the concept for use in a virtual machine controller by the specified virtual machine controller. The initialization sets up any additional components required for the concept to be used in the virtual machine.

Specified by:

initialize in interface IRuntimeConceptCtx

Parameters:

vmc - the VMController controlling the virtual machine in which this concept is to be used.

time - the time at which the initialization takes place

Throws:

VMException - if an error occurs in initializing the concept

reset

public void reset()
           throws VMException

Resets the concept removing its context and any references and additional components created to use this concept in a virtual machine.

Specified by:

reset in interface IRuntimeConceptCtx

Throws:

VMException - if in error occurs in resetting the active instance
