Class EuLab

java.lang.Object

  +--interagents.EuLab

Direct Known Subclasses:

userLab

public class EuLab

extends java.lang.Object

A EuLab is click consistent when

• There is no duplication among clickable objects
• There is no overlapping of clickable objects

It is shadow consistent when

• For every non-full object in the lab, the corresponding full object is also in the lab.

It is target consistent when

• For every target object in the lab, a corresponding clickable object is also in the lab.

The constructor. Pass mouseInfo, setup empty vectors, run clear(). @param info the mouseInfo to be used in dimensioning objects on screen

EuLab

public EuLab(int colorScheme)

EuLab

public EuLab(fundamentals.mouseInfo info)

Method Detail

clear

public void clear()

Reset the lab. Remove any object, segment set to BEFORE_PREMISE, current radius and mark reset

count

public int count()

Count objects. @return number of objects presently in lab.

elements

public java.util.Enumeration elements()

removeElement

public void removeElement(interagents.ObjectWithStatus ows)

isTargetConsistent
