      brahms.base.system.RetractFactsActivity

All Implemented Interfaces:

IExternalActivity

public class RetractFactsActivity
extends AbstractExternalActivity

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

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

• 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)
