public class Thoughtframe
extends BFrame

A Thoughtframe is a production rule. A Thoughtframe allows for the deduction of new beliefs from existing beliefs allowing for reasoning behavior for agents and objects.

A thoughtframe consists of Precondition(s) defining the conditions under which the thoughtframe can be activated and a Body which is executed when the thoughtframe is active. The body of a thoughtframe can only consist of Consequences.

As part of a thoughtframe definition variables can be defined. The variables get their values assigned through the preconditions matching with beliefs.

Method Detail

setID

protected void setID()

Sets the unique identifier.

Overrides:

setID in class BrahmsObject

delete

public void delete()

Deletes this element from the model and removes all references to this element in other model elements.

Overrides:

delete in class BFrame

createContext

public IFrameCtx createContext()

Creates a new context for this frame for use in a virtual machine.

Note: This method always returns a new instance and does not verify whether one is already created.

Specified by:

createContext in class BFrame

Returns:

IFrameCtx a context for the frame
