public class Group
extends ActiveClass

The concept of a "group" in Brahms is similar to the concept of a template or class in object-oriented programming. A group represents a collection of 'agents' that can perform similar work and have similar beliefs. A group defines the work activities (activity frames and thought frames), the initial-beliefs of members in the group and the initial-facts in the world. The difference with classes in object-oriented programming is that the relationship between a group and its members is not an IS-A relationship, but a MEMBER-OF relationship. This is why we speak of "a member of a group" instead of "an instance of a group."

Method Detail

setID

protected void setID()

Sets the unique identifier.

addMember

public boolean addMember(Agent concept)

removeMember

public boolean removeMember(java.lang.String name)

Overrides:

removeMember in class ActiveClass

delete

public void delete()

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

Overrides:

delete in class ActiveClass

isSubClassOf

protected boolean isSubClassOf(Concept concept,
                               java.util.Hashtable checked)

Checks recursively whether this group is a sub class of the specified concept, checking the concept hierarchy.

Overrides:

isSubClassOf in class ActiveClass

Parameters:

concept - the concept to be checked to see if it is a parent of this group.

checked - the table with parents already checked in the hierarchy to prevent circular loops

Returns:

true if this group is a sub class of the concept, false otherwise
