Field Detail

### drawSelection

    protected VectorSelection drawSelection

  The draw features that have been selected to draw.

### agentColorFeature

    protected ColorFeature agentColorFeature

  The generic color feature used to set the color for the primary agent type.

Constructor Detail

### AgentView

    public AgentView()

  Instantiates a new agent view.

### AgentView

    public AgentView(java.lang.String name)

  Instantiates a new agent view.

  Parameters:
    `name` - the name

Method Detail

### getDrawFeaturesObservable

    protected java.util.Observable getDrawFeaturesObservable()

  Returns an observable delegate that notifies users of draw features that a change has occurred. If you need to know when a change in draw features occur, implement observer in the appropriate class and add it to the Observerable this method returns.

  Returns:
    the draw features observable

### createFeatures

    public void createFeatures()

  Overrides:
    `createFeatures` in class `GraphicsView`

### addDrawFeature

  Parameters:
    `feature` - the feature
  See Also:
    `DrawFeature`

### removeDrawFeature

    public boolean removeDrawFeature(DrawFeature feature)

  Removes the provided draw feature.

  Parameters:
    `feature` - the draw feature to be removed
  Returns:

### getAgentColorFeature

    public ColorFeature getAgentColorFeature()

  Returns the color feature that will be used for determining agent color. The default color feature is simply the getForegroundColor() method of the agent.

  Returns:
    the agent color feature

### setAgentColorFeature

    public void setAgentColorFeature(ColorFeature agentColorFeature)

  Set the color feature that will be used for determining agent color. The default color feature is simply the getForegroundColor() method of the agent.

  Parameters:
    `agentColorFeature` - the color feature, whose object is assumed to be an agent populating this lattice

### getAgentAtPixel

  Parameters:
    `x` - the horizontal pixel location
    `y` - the vertical pixel location
  Returns:
    the agent at pixel

### drawSelectedAgent

    protected void drawSelectedAgent(org.eclipse.draw2d.Graphics graphics,

### getAgentSize

    public int getAgentSize()

  Returns a one-dimension size of pixels used to represent each cell.

  Returns:
    the agent size

### setAgentSize

    public void setAgentSize(int cellSize)

  Sets the number of pixels used to represent each cell.

  Parameters:
    `cellSize` - number of pixels per edge

### update

    public void update(java.util.Observable o,
                       java.lang.Object arg)
