All Implemented Interfaces:

IExternalActivity

public class RetractBeliefsActivity
extends AbstractExternalActivity

The RetractBeliefsActivity allows a model builder to retract beliefs about a specified subject's attribute or relation.

This activity requires two or three parameters in the Brahms java activity declaration:

• Concept source (the optional concept from which to retract a belief)
• Concept subject (the concept about which to retract a belief)
• string attribute (the name of the attribute or relation about which to retract beliefs, this attribute or relation must be declared for the type of the declared subject)
• Concept value (the optional concept value to be retracted when a relation is used, by default all values for the relation are removed)
