Constructor Detail

Actor

public Actor()

Instantiates a default actor with default label "f".

Method Detail

setCenter

public void setCenter(Point2D.Double p)

Set the center point of this actor to the given point.

Overrides:

setCenter in class GNode

Parameters:

p - the new center point, although internally the top left corner is saved as the position.

setDisplayRect

public void setDisplayRect(Rectangle2D.Double r)

Overrides super class's method so that we can adjust the display rect to account for odd shape

Overrides:

setDisplayRect in class GraphObject

Parameters:

r - the rectangle of the object.

getShape

public Shape getShape()

Actor's shape is a diamond that is inscribed within its displayRect.

Specified by:

getShape in class GraphObject

Returns:

the Shape for this object, with appropriate dimensions, etc.

See Also:

GraphObject.getShape()

draw

public void draw(Graphics2D g,
                 boolean printing)

The basic rendering method for this actor.

Overrides:

draw in class GNode

Parameters:

g - graphics context on which to perform the rendering

printing - whether we're in "printing" mode. Has no effect here, but is passed to super.draw()

drawBorder

public void drawBorder(Graphics2D g,
                       Color borderColor)

Draws the actor border, in a given color.

Overrides:

drawBorder in class GNode

Parameters:

g - The graphics context on which to draw

borderColor - the color of the wide border. Uses the actor's already-set position and size to decide where to draw

setTextLabel

public void setTextLabel(String label)

Sets the label of this actor, editing characters if any are illegal.

Overrides:

setTextLabel in class GraphObject

Parameters:

label - The new label for this actor.

adjustCustomDisplayRect

public void adjustCustomDisplayRect()

Description copied from class: GraphObject

Performs whatever custom adjustments that any sub-classes want. This method is called explicitly in some cases by Charger, but it does nothing in the GraphObject class itself. Sub-classes can override this in order to ensure their own peculiar display rect constraints (e.g., actors).

Overrides:

adjustCustomDisplayRect in class GraphObject

selfCleanup

public void selfCleanup()

Performs whatever dusting and cleaning is needed when the actor goes away. The most important cleanup is to invoke the "stopActor" method on this actor's plugin.

Overrides:

selfCleanup in class GraphObject
