Method Detail

getPluginActorName

public String getPluginActorName()

Specified by:

getPluginActorName in interface ActorPlugin

Returns:

Name by which the actor will be known throughout the system

getPluginActorInputConceptList

public ArrayList getPluginActorInputConceptList()

Assumption about input and output vectors is that inputs are numbered 1..n and outputs are numbered n+1 .. m.

Specified by:

getPluginActorInputConceptList in interface ActorPlugin

Returns:

List of input concepts (or graphs), each with a constraining type (or "T" )

getPluginActorOutputConceptList

public ArrayList getPluginActorOutputConceptList()

Assumption about input and output vectors is that inputs are numbered 1..n and outputs are numbered n+1 .. m.

Specified by:

getPluginActorOutputConceptList in interface ActorPlugin

Returns:

List of output concepts (or graphs), each with a constraining type (or "T" )

getPluginActorAttributes

public ArrayList getPluginActorAttributes()

Specified by:

performActorOperation

public void performActorOperation(GraphUpdater gu,
                                  ArrayList inputs,
                                  ArrayList outputs)
                           throws CGActorException

Specified by:

performActorOperation in interface ActorPlugin

Parameters:

gu - the current graph updater, in case the operation requires further updating

inputs - ArrayList of charger.obj.Concept

outputs - ArrayList of charger.obj.Concept, set by the operation and usable by the caller.

Throws:

CGActorException

stopActor

public void stopActor()

Perform any clean-up required by the actor when it is deleted or its graph is de-activated.

Specified by:

stopActor in interface ActorPlugin

getSourceInfo
