Class displayTree

java.lang.Object
  jason.asSemantics.DefaultInternalAction
      jildt.displayTree

All Implemented Interfaces:

jason.asSemantics.InternalAction, java.io.Serializable

public class displayTree
extends jason.asSemantics.DefaultInternalAction

Internal action to display a view of the learned tree. Trees can be displayed neither in the console or in a window frame. By default, a learner agent is enabled for displaying the learned tree in the two possible ways. For setting this option, a literal jildt_settings(displayMode, Opt) is needed, where Opt ∈ {none, gui,console, both}). When the option none is selected, the learned tree will not be displayed, even if the internal action is executed. When the option gui is selected, a frame like the one below is displayed.



When the option console is chosen, a tree like the shown below is printed in console.

clear(Y)
| + yes: clear(X)
| | + yes: success (3 examples)
| | + no: fail (1 examples)
| + no: fail (2 examples)


Option both (default), displays both gui and console modes.

Use:
jildt.displayTree(Plan, Tree)

Parameters:

• + Plan (Literal): the label of the plan which the logical decision tree has been computed for.
• + Tree (List): a list with the tree that is going to be shown. Inner nodes are formed by three elements: [literal, leftNode, rightNode]; while, leaf nodes can be formed by one or two elements: [label, number_of_examples] or [label].
  

Examples: Assuming Tree = [clear(Y), [clear(X), [success, 3], [fail, 1]], [fail,2]], and no changes in the configuration of displayMode:

• jildt.displayTree(Plan,Tree): Shows and prints the trees showed in the description.
  
• jildt.displayTree(Plan,[clear(Y), [success]]): Throws a parsing exception because of the structure of the tree.
• jildt.displayTree(Plan,Tree, X): Throws an exception due to only two arguments are needed for executing the internal action.
• jildt.displayTree(Plan, tree): Throws an exception because the second argument must be a list.
