Class AffordanceSlot

java.lang.Object
  cz.cuni.amis.pogamut.episodic.decisions.AffordanceSlot

All Implemented Interfaces:

Serializable

public class AffordanceSlot
extends Object
implements Serializable

AffordanceSlot is a node type that can be attached to Action or Intention nodes of the decision tree. AffordanceSlot is not extending the Node base class. When a slot is attached to a node, it means that in order to perform (satisfy) the node some object satisfying the slot type must be located first. Any item of the same type as the slot can be used to fill it. No two slots of the same type can be attached to one node.

These slots in the decision tree structure are only basis for creation of actual ObjectSlots in the agent's memory that will be linked with satisfying ObjectNodes.

Apart from material objects types, there can be slot of other types like time or place. These slots are also needed to be filled and they provide additional information about performance of the parent node. For example the slot of type time can be linked with the object node representing afternoon.

This method sets the unique ID of the slot. Once set it cannot be changed. It is the ID of vertex representing this node when visualizing decision tree.

Parameters:

newId - The ID of this node.

getId
